NZTA welcomes panel review report into M2PP noise


The NZ Transport Agency has welcomed the results of an expert review into the noise impacts of the Mackays to Peka Peka Expressway and says that many of the suggested mitigations are being scheduled, built or have already been completed.

“We have been working closely with the impacted communities and are acutely aware of concerns about noise. NZTA appointed noise specialists to an expert panel to review the operational noise following the Expressway’s opening in February,” Senior Manager, Project Delivery Chris Hunt says.

“The findings have been helpful and it’s encouraging that they align with many of the mitigations we are currently working hard to complete.

“We gave an assurance to the community that we would commission this review and act on its findings, and we are following through on that commitment.”

The main issues and remedies identified include:

  • ATP Rumble Strips - Prior to the report findings, The M2PP Alliance has committed to the removal of the rumble strips on the left-hand side of the outside lane. 
  • Bridge Joints – Pavement remediation will be carried out to smooth the ride over the bridges. Discussions also taking place with the joint manufacturer to determine if there is an insert that can be added to lessen noise.
  • OGPA Surfacing - The Transport Agency will accelerate planned re-sealing of the northern section, and lay a low-noise surface material Open Graded Porous Asphalt (OGPA), the same surface as the rest of the Expressway. The work will start in mid to late February (weather dependant).
  • Noise Mitigations & Building Modifications - Property owners identified in the report will be contacted by the Transport Agency to discuss further individual mitigations.

Mr Hunt says the Transport Agency will take time now to closely consider the findings of the review and provide an update to the community in February. An update on how the other work is progressing will also be provided at this time.
