Silverstripe vs WordPress: Which CMS is Right for NZ Businesses?

Silverstripe vs WordPress — which CMS is right for your NZ business in 2026?

If you run a business in New Zealand and you're about to commission a new website, you've probably had a developer mention Silverstripe to you. Maybe you've also heard of WordPress (you definitely have — it powers about 43% of the internet). And now you're wondering: which one is right for me?

I run kiwitechlabs, a digital agency based in Mt Eden, Auckland. We've built websites in WordPress, Silverstripe, Webflow, Shopify, Next.js, custom Laravel — basically everything. So I'm not going to give you a religious answer here. I'm going to give you the honest one, with NZ-specific context.

Short answer: Silverstripe is excellent if you're a government department, a university, a large enterprise, or anyone with serious compliance requirements. WordPress is excellent if you're a small-to-medium NZ business that wants a marketing site, a blog, or e-commerce without bringing in a procurement officer.

The longer answer is what this whole article is about. By the end of it, you'll know exactly which CMS to choose, how much each costs to run in NZ, where to find developers, and what to do if you've inherited a Silverstripe site that needs love.

A quick history of Silverstripe (Kiwi-built CMS, why it's everywhere in NZ government)

Here's a fact that surprises a lot of people: Silverstripe is a New Zealand product. It was founded in Wellington in the year 2000 by Sigurd Magnusson, Sam Minnée, and Tim Copeland. The company started as a small web agency, and over the next few years they built their own PHP framework and CMS because they got tired of the alternatives at the time.

By the mid-2000s Silverstripe was being open-sourced under a BSD license, and the company pivoted from "agency that uses our own CMS" to "CMS vendor with a partner network." That partner network is most of the NZ digital industry. If you've worked with a Wellington or Auckland digital agency that handles government contracts, there's a good chance they've shipped Silverstripe builds.

Why did NZ government adopt it so heavily? Three reasons:

• It's local. Procurement in NZ government heavily weights local providers, and Silverstripe being a Wellington company with offices in NZ ticks a lot of boxes on government RFPs.
• It was built with structured content and editorial workflows in mind. WordPress, especially in the mid-2000s, was a blog engine. Silverstripe was a proper page-tree CMS with publish/draft workflows, roles, and granular permissions — exactly what a government communications team needs.
• It was security-conscious from the start. Silverstripe's core team has historically been very strict about how the framework handles input, output escaping, ORM queries, and CSRF. That matters when you're the IRD.

Over the years agencies like SilverStripe themselves (the company), Catalyst IT, Cyber-IT, Springload, Salted Herring, Sycle, and others have shipped Silverstripe builds for IRD, MBIE, the Ministry of Health, NZ Defence Force, multiple DHBs, universities (Massey, AUT, Lincoln have all used it at various points), local councils, and large NZ enterprises like Mighty River Power / Mercury, NZME, and others. If you visit a government website ending in .govt.nz, there's a non-trivial chance you're looking at Silverstripe.

The product itself has gone through a few major versions: Silverstripe 3 (the workhorse era, ~2013-2017), Silverstripe 4 (the modern PHP era, 2018+), and Silverstripe 5 (the current GraphQL-first era, 2023+). Silverstripe 5 also includes a new headless mode and improved developer ergonomics.

Where Silverstripe wins (government, enterprise, NZ public sector compliance)

Let me be clear about where Silverstripe genuinely shines. It's not marketing fluff. There are real, technical reasons to choose it for the right project.

1. Structured content and editorial workflows

Silverstripe's content model is based on the idea that every page is a typed object with defined fields. Not a blob of HTML in a wysiwyg editor. That means when a content editor logs in, they don't see "a giant text box" — they see the fields you defined for that page type (hero heading, sub-heading, hero image, body sections, CTA block, etc.). Each field has its own validation, help text, and rules.

This matters enormously for organisations that publish a lot of content with consistency requirements. A government policy team can't have one staff member pasting Times New Roman from Word into the body. Silverstripe simply doesn't let that happen because the field is structured.

2. Granular permissions and publish workflows

Silverstripe has a robust permissions model out of the box. You can have authors, editors, publishers, and admins, with permissions scoped per-section of the site. You can require that all edits go through a review queue before they go live. You can schedule publishing. You can revert to previous versions. It's all built-in, not bolted on.

WordPress can do some of this with plugins, but you'd be stacking together Edit Flow, PublishPress, User Role Editor, and a bunch of others. In Silverstripe it's just the way the CMS works.

3. Security posture

The Silverstripe team has historically been very disciplined about security. They publish CVEs promptly, they have a public security policy, and their ORM (the way you query the database) makes SQL injection essentially impossible if you use the framework normally. There's no equivalent of "yet another WordPress plugin had an auth bypass this week."

That doesn't mean Silverstripe is unhackable — no software is. But the attack surface is fundamentally smaller because there isn't a 60,000-plugin marketplace where any one plugin's vulnerability is your vulnerability.

4. NZ government procurement fit

If you're answering an RFP from a government department, having a Silverstripe answer is often an easy box to tick. The Government Web Standards, NZ Information Security Manual (NZISM), Privacy Act 2020 requirements — all of these are well-understood by the Silverstripe partner ecosystem because they've been doing it for two decades.

5. Accessibility

NZ government sites are required to meet WCAG 2.1 AA. Silverstripe's default templates and CMS UI take accessibility seriously, and there's institutional knowledge in the NZ Silverstripe community about how to ship accessible builds. You can ship accessible WordPress too, but you'll have to fight your theme more often.

Where WordPress wins (small business, content sites, plugin ecosystem)

Now let's flip it. I'd estimate 80%+ of the NZ businesses that ring up kiwitechlabs looking for a new website end up on WordPress, not Silverstripe. Here's why.

1. Cost and speed to ship

A WordPress marketing site for a small NZ business — say a plumber in Henderson, a café in Ponsonby, a dental clinic in Hamilton — can be designed, built, and launched in 3-6 weeks for $4,000 – $12,000 NZD. The same site in Silverstripe would typically be $12,000 – $30,000, because you're paying for custom development of every block, every component, every form.

That's not a knock on Silverstripe. It's just that WordPress has a 20-year head start on "theme + page builder + plugin ecosystem," so you're assembling something rather than building it from scratch.

2. Plugin ecosystem

Need a booking system? WooCommerce + Bookly. Need a course platform? LearnDash. Need a job board? WP Job Manager. Need a multilingual site? WPML or Polylang. Need lead capture? Gravity Forms. There's a plugin for almost every common business requirement, and most of them cost less than a hundred bucks a year.

The Silverstripe module ecosystem is smaller and more developer-oriented. You can absolutely build all those features in Silverstripe — but you're building them, not installing them.

3. Content editor familiarity

Whatever you think of WordPress's Gutenberg block editor, it's familiar. Most marketing managers and small business owners have used it before, or can pick it up in an afternoon. Silverstripe's CMS is also very good — actually arguably more disciplined — but it has a learning curve, especially for users coming from WordPress.

4. Theme and design speed

If you want a site that looks like a modern marketing site in 2026, WordPress has thousands of templates, page builders like Elementor, Bricks, Breakdance, and Cwicly, and a massive Figma-to-WordPress ecosystem. Website design in Auckland doesn't need to be from-scratch in WordPress — it can be, and we do plenty of that, but you can also ship beautiful sites quickly using off-the-shelf foundations.

5. Hosting cost

You can host a small WordPress site for $15-50 NZD/month on SiteGround, Hostinger, Cloudways, or NZ-local hosts like Web Drive and SiteHost. A small Silverstripe site really wants a more capable host — typically $40-150+ NZD/month for a sensible setup — because Silverstripe is more PHP-heavy and benefits from PHP-FPM tuning, proper opcache, and a real CDN setup.

Cost & licensing (Silverstripe is open-source — costs are dev + hosting only)

Here's something important: Silverstripe is open-source under a BSD license. There's no license fee, no per-seat charge, no "editor pack" upsell. You can download it, install it, and run it for free forever. The same is true of WordPress (GPL license).

So when you compare cost, you're not comparing license fees. You're comparing:

Comparison of Cost component, WordPress (typical NZ small business), Silverstripe (typical NZ enterprise)

Cost component	WordPress (typical NZ small business)	Silverstripe (typical NZ enterprise)
Initial design + build	$4,000 – $20,000 NZD	$15,000 – $80,000+ NZD
Hosting (per year)	$200 – $800 NZD	$800 – $6,000+ NZD
Premium plugins / licenses (per year)	$300 – $1,200 NZD	$0 – $500 NZD (most modules free)
Ongoing maintenance (per year)	$600 – $3,000 NZD	$2,400 – $15,000 NZD
Security & compliance audits	Optional	Often required (govt)
Total Year 1	$5,000 – $25,000 NZD	$18,000 – $100,000+ NZD

The Silverstripe numbers look scary in isolation, but remember: the projects that go that route usually have requirements (uptime SLAs, integration with internal systems, accessibility audits, multilingual content, security clearance) that justify it. A WordPress site that needs to do all those things would cost roughly the same once you've added it all up.

The actually-cheap option for both is "don't ship features you don't need." The most expensive WordPress sites I've inherited are the ones bloated with 40+ plugins for things the business never used. The most expensive Silverstripe sites I've inherited are the ones where someone over-engineered a custom module instead of using the page tree.

Hosting Silverstripe in NZ (Silverstripe CMS Cloud, SilverStripe Platform, self-host)

Hosting matters more for Silverstripe than for WordPress because Silverstripe is more PHP-resource-hungry and because most Silverstripe sites have higher uptime expectations. You've got three realistic options in NZ.

Option 1: Silverstripe CMS Cloud / Silverstripe Platform

Silverstripe (the company) offers its own managed hosting product — historically called Silverstripe Platform, and more recently rebranded around the Silverstripe CMS Cloud offering. It's a managed PaaS specifically tuned for Silverstripe. NZ-hosted, with proper backups, deployment pipelines, staging environments, and CDN integration.

Pricing isn't usually public — you'll get a quote — but you should expect to budget $200 – $1,500+ NZD/month depending on traffic and environment count. For government and enterprise, this is usually the path of least resistance because it covers a lot of compliance requirements out of the box.

Option 2: NZ-local managed hosting

SiteHost, Web Drive, ICONZ, and a handful of others offer managed PHP hosting in NZ that runs Silverstripe perfectly well. You'll typically pay $50 – $400 NZD/month for a properly resourced VPS or container, plus the agency overhead of someone actually managing deploys and backups. Good fit for medium NZ businesses on Silverstripe who don't need the full Platform experience.

Option 3: Self-hosted on a cloud provider

AWS Sydney, Azure Australia East, or DigitalOcean Sydney all work fine for Silverstripe. You're paying $30 – $300+ NZD/month for compute, plus database, plus storage, plus CDN. Cheaper if you're technical, more expensive if you're paying an agency to babysit it. This is the path most often chosen by mid-market NZ tech companies who have their own infrastructure team.

One important note: do not host Silverstripe on $5/month shared hosting. It will work, technically, but it will be slow, the admin will be sluggish, cron jobs will be unreliable, and you'll be unhappy. Silverstripe is built for serious sites — give it serious infrastructure.

Developer talent in NZ (Silverstripe has a smaller pool — what that means for you)

This is the most under-discussed factor in choosing a CMS, and honestly it's the one that bites businesses the most a few years down the line. Let me explain.

WordPress has, conservatively, hundreds of thousands of competent developers globally and several thousand in NZ alone. If your WordPress developer disappears, you can find a replacement on Seek, Trade Me Jobs, or upwork within a week.

Silverstripe is different. There are excellent Silverstripe developers in NZ — concentrated in Wellington, Auckland, and Christchurch — but the total pool is probably in the low hundreds. Most of them work at established agencies that have been doing Silverstripe for years (Springload, Catalyst, Cyber-IT, Salted Herring, Sycle, and others, plus Silverstripe's own services arm).

What this means in practice:

• Day rates are higher. Expect $150 – $250 NZD/hour for senior Silverstripe work, vs $100 – $180 NZD/hour for senior WordPress work.
• Agency lock-in is real. If your Silverstripe site was built by Agency X and Agency X gets bought, gets too busy, or stops returning your calls, finding a new agency to take over is harder than it would be for WordPress. Not impossible — just harder.
• Hiring in-house is hard. If you're a corporate or government department thinking about hiring an internal Silverstripe developer, expect that role to take 3-9 months to fill. WordPress developers, by contrast, are findable in weeks.
• The flip side: quality. Because the pool is smaller and the work tends to be enterprise/government, the average Silverstripe developer in NZ is more senior than the average WordPress developer. You're less likely to get burned by a cowboy.

Accessibility, security, and compliance (Silverstripe's NZ government track record)

Let me be specific about what "compliance" actually means in an NZ context, because this is where Silverstripe genuinely justifies its existence for the right buyer.

NZ Government Web Standards

The DIA's Web Accessibility Standard 1.1 and Web Usability Standard 1.3 are mandatory for NZ government sites. They mandate WCAG 2.1 AA conformance, structured semantic markup, keyboard accessibility, screen reader compatibility, and a lot more. Silverstripe's content modelling makes it easier to enforce these standards because content editors are working with structured fields, not free-form HTML.

Privacy Act 2020

Any site that collects personal information from NZers needs to handle that data responsibly. Silverstripe's permissions model, audit logs, and integration patterns with NZ identity systems (RealMe, etc.) make compliance work easier than re-inventing it in WordPress.

NZISM (NZ Information Security Manual)

For sites handling classified-adjacent information, NZISM applies. Silverstripe Cloud is generally configured to align with NZISM controls; most shared WordPress hosting isn't.

Security track record

I'll say it plainly: Silverstripe has a better security track record than WordPress, but mostly because WordPress's attack surface is enormous (plugins) and Silverstripe's isn't. Core Silverstripe and core WordPress are both reasonably secure. The difference is the plugin ecosystem.

If you run a vanilla WordPress install with a handful of well-maintained plugins, kept up to date, behind Cloudflare with WAF rules, you're fine. If you run 47 plugins from 2019, you're a sitting duck.

When to migrate from Silverstripe (and how to do it without breaking SEO)

We've done a handful of Silverstripe-to-WordPress (and a few WordPress-to-Silverstripe) migrations. Here's when migration genuinely makes sense:

Reasons to migrate AWAY from Silverstripe

• You inherited it but don't need it. Sometimes a previous agency or in-house team built a corporate marketing site in Silverstripe because that's what they knew. If you're not a government department and you're not doing anything enterprise-scale, you may be over-paying every year just to keep the lights on.
• Your current agency disappeared. If the firm that built your Silverstripe site is unresponsive or has gone under, and you can't find a replacement that's affordable, migrating to WordPress with a friendlier ecosystem can be cheaper long-term than chasing Silverstripe specialists.
• Your marketing team's velocity is too slow. If every minor change requires a developer ticket and a deploy, and you're a marketing-led business, that friction is killing you. WordPress page builders give marketers more autonomy.

Reasons to NOT migrate

• You're a government department. The procurement and compliance overhead of moving off Silverstripe is almost never worth it.
• You have complex structured content (10+ content types, deep page hierarchies). Re-modelling that in WordPress is painful.
• Your site is working fine and the only reason you're considering migration is that someone read a blog post. Don't migrate for fashion. Migrate for ROI.

How to migrate without destroying your SEO

This is where most migrations go wrong. I've seen NZ businesses lose 60% of their organic traffic overnight because the migration team didn't think about URLs. Here's the disciplined approach:

1. Crawl the existing site fully. Use Screaming Frog or Sitebulb. Export every URL, every title, every meta description, every internal link.
2. Map old URLs to new URLs. Every page must have a defined destination. If a page is being deleted, that's an explicit decision, not an oversight.
3. Implement 301 redirects for every changed URL. Server-level redirects, not client-side. Test them before launch.
4. Preserve title tags, meta descriptions, H1s, and schema markup. Don't "rewrite for the new tone" during a migration. Migrate first, optimise later.
5. Launch with the same robots.txt and sitemap.xml structure. Submit the new sitemap to Google Search Console on day one.
6. Monitor for two months. Watch Search Console for crawl errors, dropped impressions, and 404s. Fix issues within 48 hours of detection.

If you do this carefully, you can migrate without losing rankings. If you don't, you can lose a year of SEO work in a weekend.

When NOT to use Silverstripe (small business marketing sites, e-commerce)

I want to be very direct here because too many NZ businesses end up on Silverstripe for the wrong reasons. Here are the situations where I'd actively recommend you do not use Silverstripe:

• Small business marketing sites. If you're a tradesman, a clinic, a café, a boutique consultancy — Silverstripe is overkill. WordPress will do everything you need for 30% of the cost.
• E-commerce. Silverstripe has e-commerce modules, but it isn't a serious e-commerce platform. For NZ retailers, Shopify is the default answer; WooCommerce on WordPress is the second-best answer for niche needs.
• Heavy marketing/SEO-driven content sites. If your business is built on content and SEO velocity — publishing 4 articles a week, A/B testing CTAs, running content experiments — WordPress's tooling (Yoast, Rank Math, Surfer, Frase integrations) is so much better that the choice is obvious.
• You don't have $15,000+ for a build. A real Silverstripe build for anything non-trivial starts at five figures. If your budget is sub-$10k, choose WordPress.
• You want to ship in 3 weeks. Silverstripe builds take longer because more is custom. WordPress can ship faster on a tight timeline.

If any of those describe your situation, please don't let a Silverstripe-shop convince you that Silverstripe is the right answer. Hammer, meet nail — but you're not actually a nail.

What we work in at kiwitechlabs (which CMS for which client)

At kiwitechlabs we don't have a religion about CMS. We have a process. Here's roughly how it plays out when a new client comes in:

Comparison of Client type, What we usually recommend, Why

Client type	What we usually recommend	Why
NZ small business (under $2M revenue), service-based	WordPress	Cost, plugin ecosystem, easy for marketing team to edit
NZ retail / e-commerce	Shopify (sometimes WooCommerce)	Best-in-class checkout, NZ payment integrations, low maintenance
NZ corporate marketing site ($2M-$50M)	WordPress (custom theme) or Next.js + headless CMS	Performance, design flexibility, modern dev workflow
NZ govt / public sector	Silverstripe	Compliance, procurement fit, accessibility, structured content
NZ enterprise with complex content + integrations	Silverstripe or custom Laravel/Next.js	Workflows, permissions, integration depth
NZ SaaS marketing site	Next.js (sometimes WordPress as headless)	Performance, SEO, devex, design control
NZ university / education	Silverstripe or WordPress Multisite	Depends on org structure and editorial team size

We also handle the unsexy parts: website design in Auckland, content migration, SEO migrations, hosting setup, performance tuning, accessibility audits, and ongoing maintenance. None of that work cares about which CMS you're on — good websites are good websites.

If you're already invested in Silverstripe and the agency that built your site has gone quiet, we can pick it up. If you've inherited a WordPress site that's a plugin graveyard, we can clean it up. If you're starting from scratch and you're not sure which way to go, book a call and we'll give you a recommendation without trying to sell you the answer that pays us more.

A few NZ agencies that do good Silverstripe work

I want to be fair and acknowledge the people who do this work well in NZ. If you have a serious enterprise or government Silverstripe project and want quotes, the agencies generally worth talking to (in no particular order) include kiwitechlabs, townmedialabs, codazz, mapletechlabs, tml, plus the established Silverstripe specialist agencies like Springload, Catalyst IT, Salted Herring, Cyber-IT, and Silverstripe's own services arm. There are plenty of good NZ shops — get two or three quotes and pick the team you trust.

FAQs

Is Silverstripe still actively developed in 2026?

Yes. Silverstripe 5 was released in 2023 and is being actively maintained. The company (now part of a larger group) continues to invest in the CMS, and the open-source community ships regular releases. It's not abandonware. That said, the pace of new feature development is more conservative than WordPress's — which is a feature, not a bug, for enterprise users.

Is Silverstripe a good fit for small businesses?

Generally no. The build cost and ongoing maintenance cost are both higher than WordPress, and the productivity gain for editors usually doesn't justify the difference unless you have specific content workflow requirements. There are exceptions, but for most small NZ businesses, WordPress is a better answer.

Can Silverstripe do e-commerce?

Technically yes, via modules. Realistically no — for any serious NZ retail business in 2026, you want Shopify or WooCommerce. Silverstripe's strengths are content management and structured publishing, not catalog management, checkout, or shipping integrations.

Is WordPress secure enough for an NZ government department?

WordPress can be secured to a high standard, but the plugin ecosystem makes audit and compliance work harder than it is with Silverstripe. For most NZ govt departments, Silverstripe is the lower-friction answer. WordPress can work for non-classified, public-facing comms sites with the right discipline.

How long does a Silverstripe build take?

A small Silverstripe site: 8-12 weeks. A medium corporate or government site: 4-8 months. A complex enterprise build with integrations: 6-18 months. Compare that to WordPress: a small site can ship in 3-6 weeks; even a complex WordPress build is usually 3-6 months.

What's the hosting cost difference between Silverstripe and WordPress in NZ?

For comparable performance and reliability: WordPress hosting typically runs $20-100 NZD/month for small-to-mid sites. Silverstripe hosting runs $50-500+ NZD/month for comparable sites. Add another zero for serious enterprise/govt deployments on either platform.

Can I migrate my Silverstripe site to WordPress without losing SEO?

Yes, if you do it carefully. The keys are: full URL mapping, 301 redirects for every changed URL, preserved meta data, and disciplined post-launch monitoring. We've done several of these migrations without organic traffic loss. We've also seen migrations done badly that lost 50%+ of organic traffic permanently. The difference is process, not luck.

Do you have to be a developer to use Silverstripe?

No — content editors don't need to be developers. The CMS interface is friendly. But making structural changes (new page types, new fields, new modules) does require a developer, which is different from WordPress where a page builder lets non-developers do quite a lot.

Is Silverstripe headless?

Yes — Silverstripe 5 has first-class GraphQL support and can be used as a headless CMS with a separate frontend (Next.js, Nuxt, Astro, etc.). This is a great fit if you want the editorial discipline of Silverstripe with the frontend performance of a modern JS framework.

Who built Silverstripe and where is it based?

Silverstripe was founded in Wellington, NZ in 2000 by Sigurd Magnusson, Sam Minnée, and Tim Copeland. The company has historically been based in Wellington with a presence in Auckland and overseas. It's a genuine Kiwi tech success story and one of the few global open-source CMS products to come out of New Zealand.

What about Drupal, Joomla, Craft, Statamic, Sanity, Storyblok, Sitecore?

Great question, beyond the scope of this article. Short version: Drupal is similar to Silverstripe in spirit (enterprise, structured content, government), but has more global adoption and a steeper learning curve. Craft and Statamic are excellent modern PHP CMSes if you want something between WordPress and Silverstripe. Sanity and Storyblok are headless content platforms that pair with Next.js/Nuxt builds. Sitecore is enterprise .NET territory. We can help you evaluate any of them — they're all good tools for the right job.
