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.


February 2021

The Owhiro Bay sea wall construction work is close to completion and we are currently reinstating the footpath and handrail.

We are also carrying out unscheduled but necessary works, building new stairs on the car park end of the sea wall to provide additional public access to the beach, and making repairs to the cavity damage beneath the footpath following last year’s high sea swells.

Due to the additional works, the one lane traffic management will continue until mid-late March 2021.

November 2020

The construction phase is progressing well with seven of the ten x 6m long sections have been poured.

In the upcoming weeks, work will continue until the site is shut down for the Christmas/New Year holidays with contractors returning to site on 11 January 2021.

October 2020

Progress is going well with the construction phase of this project. So far, two of the ten sections have been poured with each section being 6 metres long.

In the next four weeks, preparation for the reinforcing and framework will be done for the next two sections.

September 2020

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-end March 2021.

What to expect


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.


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


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
