What we are

TTAP — short for Tohunga Transport Advisory Partners — is a small, senior, NZ-based transport consultancy. "Tohunga" is te reo Māori for expert: a skilled practitioner whose authority comes from depth of practice. We chose the name as a commitment. Our team is structured so that every project is led by people with 15-plus years of practice across NZTA, councils, and major infrastructure programmes.

What we believe

Shaping the future of sustainable and innovative transport solutions that enhance the quality of life for our own communities, environment, and future generations.

Resilience

Adapting to challenges with agility and foresight to create robust and enduring transport networks.

Sustainability

Prioritising eco-friendly practices to ensure a greener future for generations to come.

Collaboration

Building strong partnerships to foster a shared vision of efficient and integrated transport systems.

Innovation

Embracing cutting-edge solutions to revolutionise transport planning and infrastructure.

How we work

  • Senior-led delivery. No grad-led work. The senior names in the proposal are on the project from kickoff to completion.
  • Evidence-based recommendations. Every business case, design and review is grounded in measured data — FWD, traffic counts, modelled forecasts, condition surveys.
  • Local accountability. One Wellington office. Local knowledge of NZ regulations, councils, contractor capability and supply chains.
  • Transparent commercials. Fixed-fee where the scope is fixed; T&M where it isn't. Clear progress reporting against scope and budget.

Where we work

Headquartered at Level 3, 29 Waterloo Road, Lower Hutt. We deliver projects across Aotearoa New Zealand — from Northland to Southland — with focus areas in Wellington, the Kāpiti Coast, the Bay of Plenty, and Tauranga.
