Flow Transportation Specialists Limited

What Flow Transportation Specialists Limited does

Flow Transportation Specialists Limited is a privately held New Zealand transport planning and traffic engineering consultancy headquartered in Auckland, founded in 2005 by Angie Crafer and Bronwyn Coomer-Smit. The firm operates with a team of approximately 21 staff including directors, technical directors, senior associates, principals, and engineers, and is self-described as one of New Zealand's premier transport consultancies. Its services span eight core areas: land use development and transport assessments, pedestrian infrastructure, cycling infrastructure (including cycle demand modelling via the proprietary Auckland Cycle Model), public transport planning, travel demand management, road layout and street design, parking, and transport modelling using industry-standard simulation software (SATURN, AIMSUN, S-PARAMICS, SIDRA, LINSIG).

Flow generates revenue through professional services fees negotiated on a per-project basis, typically procured via competitive tender from public sector clients and direct engagement with private sector developers. Its customer base is dominated by New Zealand central and local government — including Waka Kotahi NZ Transport Agency, Auckland Transport, Auckland Council, Wellington City Council, Greater Wellington Regional Council, and HLC/Kāinga Ora — alongside private developers, healthcare operators, educational institutions, and, increasingly, international development organisations such as UNDP. Project work spans strategic infrastructure (City Rail Link, Northern Corridor Improvements, Auckland Light Rail, Let's Get Wellington Moving), housing programmes, resource consent transport assessments, road safety audits, and bespoke emissions modelling (the Samoa Transport Emissions Model). Distribution is direct, with no third-party channels, and marketing relies primarily on professional reputation, project portfolio, and relationships rather than digital demand generation.

The firm is privately held with no disclosed external investors or institutional funding. Its current leadership comprises Managing Director Angie Crafer, Director Ian Clark, Director Terry Church (promoted in 2023), and Technical Directors Phil Harrison, Nerissa Harrison, and Michael Jongeneel; co-founder Bronwyn Coomer-Smit retired in mid-2025 retaining a minor shareholding. Geographic reach centres on New Zealand with growing Pacific Islands engagements in Samoa and Fiji.
