Owhiro Bay sea wall replacement

We are ensuring the resilience of Owhiro Parade by rebuilding the sea wall to support the roading infrastructure above it and to make it safer for the public.

A trench dug next to a road, with a row of cones blocking off traffic.

September update

The construction phase of the Owhiro Bay sea wall replacement is progressing well and we are one week ahead of schedule.

50% of the existing seawall has been demolished, and the bank has temporarily been stabilised with the installation of galvanised ground anchors.
We thank you for your patience.

The construction work started in August 2020 and will be completed in mid-February 2021.

What to expect

Access

Vehicle and pedestrian access will be restricted at times while the work is underway. There will be a one-lane traffic light system in place for the duration of works with occasional stop/go to accommodate construction vehicles and works.

Keep your distance

Please stand well back from the action, follow the directions of workers, warn children about the potential dangers, and keep your pets away from the worksite. There will be cones and barriers, and surfaces may be uneven. If you are walking in this area, please take extra care to avoid potential trip hazards, particularly when it’s dark.

Delays

In the event of unsuitable weather or other unforeseen circumstances, the construction work may be delayed.

Background

Owhiro Bay Parade is classified as a ‘primary collector’ route under the One Network Road Classification (ONRC) system by NZ Transport Agency (NZTA).

This means that it’s a locally important road that provides a primary distributor/collector function, linking significant local population areas (Island Bay and Owhiro Bay suburbs) with the central city.

In 2010, the Council identified structural deficiencies in the 159 meters length sea wall –a circa 1930s mortared brick structure– on Owhiro Bay Parade, and initiated a programme to replace the entire length. 

Sections have been replaced in stages since 2010:

  • Stage one: 2010 – 35 meters
  • Stage two: 2015 – 45 meters
  • Stage three: 2018 – 18 meters
