New Zealand's RDTI: A Successful Innovation Incentive with Room for Improvement (2026)

Is New Zealand’s R&D Tax Incentive a Game-Changer or Just Another Policy? A Five-Year Review Sparks Debate

The New Zealand government’s bold move to stimulate innovation through the Research and Development Tax Incentive (RDTI) has been under the microscope. A recent five-year review, conducted by Motu Economic and Public Policy Research and The University of Otago, reveals both triumphs and areas ripe for improvement. But here’s where it gets controversial: while the RDTI appears to be a success on paper, some businesses argue it’s not all smooth sailing. Let’s dive into the findings and uncover what’s really at stake.

Launched in April 2019, the RDTI offers a 15% tax credit on eligible R&D expenditure, aiming to broaden access to innovation support. The review’s key question: Is the government getting its money’s worth? The answer, it seems, is a resounding yes—but with caveats. Here’s a breakdown of the highlights:

  • Economic Impact: The RDTI is projected to deliver a 4.2x return on government investment, boosting New Zealand’s GDP by $6.8 billion over five years. That’s a significant bang for the buck.
  • R&D Spending Surge: Firms supported by the RDTI spent an additional $1.833 billion on R&D, with an average annual increase of $274,000 per firm.
  • Innovation Gains: Supported firms saw a 6.1 percentage point increase in innovation rates, alongside higher growth in output, capital, and employment—though productivity gains remain elusive, likely due to the short evaluation period.
  • Global Competitiveness: While New Zealand’s RDTI holds its own, Australia’s scheme offers more flexibility for SMEs and overseas R&D, though recent changes there have tightened eligibility.

But here’s the part most people miss: Despite its successes, the RDTI isn’t without its critics. Stakeholder feedback highlights several pain points:

  • High Compliance Costs: Smaller firms, especially those spending under $300,000 on R&D, find the administrative burden disproportionate.
  • Processing Delays: Unpredictable timelines for Supplementary Returns create cash flow challenges for businesses.
  • Software Eligibility Rules: Current guidelines are misaligned with iterative software development processes, leaving some firms frustrated.
  • Policy Instability: Frequent changes undermine long-term planning and confidence.

And this is where it gets controversial: While the report recommends maintaining stability and streamlining compliance, it also notes that proposed changes like tiered credit rates or higher overseas expenditure caps could have negative net impacts. Is the government striking the right balance, or are these recommendations enough to address the concerns?

Deloitte’s Take: Over time, many businesses have grown more comfortable with the RDTI, particularly in software development, where claims are robust. However, challenges remain, especially in aligning eligibility rules with real-world practices. We encourage businesses to reach out if they’re unsure whether their R&D activities qualify.

What’s Next? The government’s silence on the report leaves room for speculation. Will the RDTI evolve as part of the Going for Growth initiative? And how will increased scrutiny of expenditure claims shape future applications? One thing’s certain: the RDTI is a cornerstone of New Zealand’s innovation strategy, but its future hinges on addressing these lingering issues.

Thought-Provoking Question: Is the RDTI truly globally competitive, or does New Zealand need bolder reforms to stay ahead in the innovation race? Share your thoughts in the comments—we’d love to hear your perspective!
