Ian Clark

Ian Clark has over 30 years in transport planning and transport modelling. Between 1987 and 1997 he worked in London, before moving to New Zealand.

Ian is known as an expert in transport modelling.  In addition to overseeing traffic/transport modelling tasks at Flow, he has also acted as the peer reviewer, overseeing the development of transport models for the Waikato region, the Western Bay of Plenty (including Tauranga/Mount Maunganui), Dunedin and Queenstown.

Between 2008 and 2016 Ian was the inaugural chairman of the New Zealand Transport Modelling User Group (“NZMUGS”), and he continues to play an active role in the Group, fronting the development of guidelines on travel demand forecasting, and representing NZMUGS on the equivalent group in Australia (the AITPM Transport Modellers Network).



Over the last 20 years in New Zealand he has been involved in the transport planning of many major projects throughout the country, including:

  • Studies relating to additional or improved crossings of the Waitamata and Manukau Harbours, both in Auckland
  • Involvement in the redevelopment of Eden Park, for the Rugby World Cup
  • Responsible for the transport assessment of the Auckland City Rail Link, including an assessment of the traffic effects in the Auckland CBD during the construction of the project
  • Responsible for the transport assessments relating to the NZ Transport Agency’s Southern and Northern Corridor Improvements projects.  Both projects are currently under construction.

"I am proud of what we have achieved at Flow, and for playing my part in establishing our reputation for excellence in strategic transport planning and traffic/transport modelling."
