MacKays to Peka Peka Expressway

Role: Expert acoustic and vibration consultant
Client: Environmental Protection Authority
Duration: 2011 – 2012


The Mackays to Peka Peka Expressway (M2PP) is an 18km section of the Wellington Northern Corridor, a ‘road of national significance’ that runs from Wellington Airport to Levin. Following a route some distance to the west of the existing State Highway 1, the four-lane M2PP expressway will pass through areas of Raumati, Paraparaumu and Waikanae. It’s a four-year, $630m project led by the New Zealand Transport Agency (NZTA).

The challenge

The Environmental Protection Agency (EPA) asked us to carry out completeness checks on five technical reports and the ‘construction noise and vibration management plan’ prepared by NZTA and its project team.

Our solution

Following the EPA’s recommendations, as this was considered to be a proposal of national significance, the Minister for the Environment referred the NZTA’s ‘notice of requirement’ and resource consent applications to a board of inquiry.

Our experience and expertise in large projects of this nature ensured the related reports and assessments lodged with the board of inquiry were robust and complete. This helped to:

  • Enable well-informed decision-making
  • Avoid unnecessary delays and re-work for everyone involved
