Waikato Regional Transport Model (WRTM)

The Waikato Regional Transportation Model (WRTM) is a multi-modal strategic model that has been used across the Waikato since 2007. The purpose of the model is to enable integrated planning of land use and transport proposals to be analysed, and possible changes in policies to be evaluated.

The WRTM is a strategic level model and currently plays an important role in the assessment of integrated land use and transport planning initiatives and the assessment of proposed changes. The WRTM assists with planning macro level responses and understanding a range of modelled future scenarios. Specifically the WRTM assists with:

  • forecasting future traffic volumes for investment and maintenance;
  • testing alternative land use policy analysis and spatial planning;
  • testing the merits of alternative transport networks (including road and public transport);
  • calculation of future benefits for economic evaluation of transport projects; and
  • providing inputs into other tools to undertake more detailed intersection or urban modelling analyses.


The geographically coverage of the WRTM includes the Waikato Regional Council area from the Auckland boundary in the north, up to and including the Taupo District in the south, and from the west coast of the Waikato to the east, including the Western BOP, Rotorua District and Tauranga City. These areas outside of the Waikato region are important in considering inter-regional journeys.

The WRTM is a jointly owned model and is currently managed by the WLASS who have allocated the management function to the RATA Manager on behalf of the owners. The ownership structure of the WRTM is unique to the Waikato Region and the original ownership and shareholding has remained throughout various Governments and Governmental Department changes. This long-standing agreement along with strong collaboration among the shareholding parties throughout has made the WRTM an enduring success.
