Top CRO Agencies in New Zealand – Why Tui Experiments Stands Out

Introduction

Most enterprise websites in New Zealand underperform. Traffic is healthy. Design looks good. But conversions don’t grow.

The cause? Unclear user journeys, wasted testing effort, and data trapped in silos. That’s where Conversion Rate Optimisation (CRO) comes in – helping businesses turn existing traffic into measurable growth through evidence-based experimentation.

In this article, we’ll highlight the top CRO agencies in New Zealand, and explain why Tui Experiments stands out for large organisations that want sustainable, evidence-backed results.

What does a CRO agency do in New Zealand?

A CRO agency in New Zealand helps businesses improve their website performance by turning data into action. They analyse user behaviour, design and run experiments, and optimise funnels to increase conversion rates.

The goal isn’t more traffic – it’s more revenue from the traffic you already have.

The state of CRO in New Zealand

CRO has moved from being a design tweak or marketing experiment to a strategic growth lever. Yet many enterprise teams still face similar barriers:

• Fragmented testing without clear prioritisation

• Limited bandwidth to execute continuous programs

• Unclear ROI from experimentation

• Tools and data scattered across teams

That’s why choosing a CRO partner with a proven framework matters.

Top CRO agencies in New Zealand

Several agencies are known for their work in digital optimisation, analytics, and experimentation. These are the ones that consistently deliver measurable results:

1. CSA Data Consulting (formerly Catchi)

CSA Data Consulting brings years of experience in digital analytics and experimentation. Their strength lies in advanced data maturity frameworks, conversion tracking, and measurement strategy. They help corporate clients uncover growth opportunities through structured, evidence-based testing.

2. PureSEO

PureSEO is one of New Zealand’s most established digital performance agencies. Beyond search, they focus on technical optimisation, analytics, and conversion alignment for ecommerce and enterprise websites. Their integrated approach bridges traffic generation and on-site conversion.

3. Tui Experiments

Tui Experiments is a specialist CRO and experimentation consultancy. Unlike generalist agencies, CRO isn’t one of many services – it’s the entire focus. The team blends analytics, psychology, and UX research to identify friction and create measurable growth.

What makes Tui Experiments different from other CRO agencies?

1. End-to-end delivery

Tui Experiments handles the full process – analytics, research, hypothesis design, test execution, and reporting. There’s no outsourcing or broken handover between teams. Every experiment links directly to measurable revenue outcomes.

2. Proven corporate experience

Thijs van Lierop worked with clients like Air New Zealand, Kathmandu, Les Mills, VodafoneZiggo, and AA Insurance, Tui Experiments understands corporate environments where testing must be statistically valid, compliant, and scalable.

3. Transparent, evidence-based work

All tests follow clear hypotheses, confidence thresholds, and post-test documentation. Clients access dashboards and learning archives, ensuring visibility and accountability across teams.

4. Direct senior involvement

Founder Thijs van Lierop works directly with clients – not through account managers or offshore teams. That hands-on approach delivers pragmatic insight and faster iteration.

5. Capability building focus

Rather than creating dependency, Tui Experiments trains in-house teams in CRO strategy, test ideation, and analytics interpretation. Over time, clients build their own internal experimentation culture.

Which industries benefit most from CRO in New Zealand?

CRO delivers measurable results for industries where digital performance directly impacts revenue:

• Insurance and Banking – Simplifying quotes and online policy journeys.

• Travel and Tourism – Streamlining booking flows and upsells.

• Retail and Ecommerce – Optimising product discovery and checkout conversion.

• SaaS and Telco – Improving lead-to-trial or trial-to-paid conversion rates.

Tui Experiments’ clients span all of these sectors, applying testing frameworks that uncover friction and validate solutions quickly.

Key takeaways

Tui Experiments isn’t a marketing agency with a CRO department – it’s a dedicated experimentation consultancy built for enterprise performance.
