Jan Heijs has more than 35 years’ experience in New Zealand and The Netherlands, offering strategic advice in stormwater and wastewater management, water sensitive design, green infrastructure and asset management. He has experience in and knowledge of local government processes and the Resource Management Act.

Jan is a strategic thinker and is known for his ability to translate complex issues into easy to understand reports and presentations, tailored to the audience. He has been involved in many reorganisations and change management projects, including Auckland’s amalgamation in 2010.

Jan has built his reputation by leading many local and planning processes. He managed a strategic wastewater network planning project, known under the name project CARE, which included cost benefit analyses, cost optimisation, network performance target setting, public consultation and master planning. As part of this project, Jan became one of the few experts in inflow and infiltration.

Another key project was the Long Bay structure plan. This was a New Zealand first, where water sensitive design was recommended at a catchment-wide scale and successfully argued through the Environment Court. Jan subsequently led input into stormwater management related plan changes in North Shore and the Auckland Unitary Plan. He also successfully led wastewater and stormwater catchment planning teams.
