Alert Level 3

This project is critical and essential and will start up under Alert Level 3. All of the necessary safety precautions will be followed, including the use of PPE.

Update 20 July 2021

We will shortly be connecting a new service into the water supply network in your area. This means we have to turn off the supply to your home for a short time. Following a successful trial, the shutdown will affect the following properties: 1-20 Pinehaven Road, 38-40 and 48 Blue Mountains Road, Pinehaven.
We expect this to take place from:

10 am - 2 pm Wednesday 21 July 2021

The water will be back on as soon as possible, but we recommend you fill up some containers with water before the time above and avoid running your dishwasher, washing machine or any appliances that use water. It’s best not to use water from your hot water cylinder either as the cylinder may get damaged if the water level gets too low.


When the water supply is turned back on, it’s a good idea to open a cold tap slowly then let it run for a minute or so to clear any air bubbles that may have entered the system. Air can cause the water to turn a milky colour, but this won’t affect the taste, and should clear quickly.

If you have any questions about this work please contact any of the following:

Update 18 November

We are notified on Tuesday 19 November 2019 for the consenting process and the hearing will be in early March 2020.

Update 21 August

We will soon be getting under way with further investigations to locate services for the Pinehaven Stream Improvements project.

We will be doing more site investigation to complete the design work for the proposed new culvert at Pinehaven Road. The investigations are expected to take place within the carriageway, road and footpath areas.

The investigation work will take about two weeks from 26 August to 7 September 2019, weather dependent.   Hours of work will generally be 7am - 6pm Monday to Saturday.

Work areas will be fenced off, and it is not expected that traffic flows or access to properties will be significantly disrupted. The bus stops on Pinehaven Road may need to be temporarily relocated, and they will be repositioned a few meters up the road.

On-street parking in the area alongside the worksite may be restricted, and we ask that you please do not park your vehicle within the coned areas. This will help us get our work done as quickly as possible.

If you have any questions regarding this project, please contact:

Update 12 July

Our site investigation work is progressing well. Investigations at Sunbrae Drive are complete, and the road and pathways have been re-sealed. The work at Pinehaven Road is 45% complete, and work will continue into Monday next week (15 July).

Update 8 July 2019

In refining our design, we need to do some more topographic survey work. This means that we would like to come onto your property to take some measurements. In most cases, this would take no more than a few hours.


The contractor engaged to do this work is Downer. Before entering your property, they will knock on your front door; they do not need to enter your home.


If, during the visit, no one is at home, they will leave a card in your letterbox informing you that they have visited your property to collect survey data. If you have a dog at home, please let Downer staff know.


As well as surveying in private properties, much of the survey work will happen in public areas, such as Willow Park and Pinehaven Reserve and road reserve, so it’s likely that you will see the surveyors about.


The work will begin on 10 July 2019 and will take a couple of weeks to complete.

Please call Tim Haylock, Downer Project Manager, regarding organising a suitable time for the surveyors to come to your place.

Update 7 July 2019

We will soon be getting under way with investigations to locate services for the Pinehaven Stream Improvements project.

We will be doing site investigations to complete the design work for the proposed new culverts in Sunbrae Drive and in Pinehaven Road. The investigations are expected to take place within the carriageway, road and footpath areas.

The investigation work will take about two weeks from 10 July to 24 July 2019 weather dependent.  

Hours of work will generally be:

  • 7am – 6pm Monday to Saturday - Sunbrae Drive
  • 7am - 6pm Monday to Saturday- Pinehaven Road

Work areas will be fenced off, and it is not expected that traffic flows or access to properties will be significantly disrupted. Bus stops on Sunbrae Drive and Pinehaven Road will need to be temporarily relocated. The bus stops on both sides of Sunbrae Drive will be moved up the road near to the intersection with Tapestry Grove. The bus stop on Pinehaven Road will be moved a few meters up the road.

On-street parking in the area alongside the worksite may be restricted, and we ask that you please do not park your vehicle within the coned areas. This will help us get our work done as quickly as possible.

Update - 17 December 2018

In 2017, preliminary ground investigations were completed for the Pinehaven Stream Improvements project. These investigations were sufficient to generally characterise the soil conditions at the site and inform the concept design for the proposed stream works.

Supplementary geotechnical data is required in order to support the detailed design and building consents. It will also allow the contractor to evaluate the construction methodology.

Geotechnical investigations including five (5) machine drilled bore holes, three (3) hand augers and five (5) test pits will be undertaken within Whitemans Road, Blue Mountains Road, Pinehaven Road, and Birch Grove over January 2019.

Drilled bore holes

The drill rig to be used for this project has a small footprint, which minimises site impact.

 Test pits

Test pits will be completed using a rubber tracked 1.6T digger, for digging a 2m test pit.

Greater Wellington Regional Council and Upper Hutt City Council have been working together to improve flood protection in the Pinehaven Catchment. The Floodplain Management Plan www.gw.govt.nz/pinehavenstream/  details the Plan’s vision for a prosperous and safe community that proactively manages the risk of flooding. Delivering this vision involves a structural improvements project and planning controls through the Upper Hutt District Plan.

The project works will be focused on key flooding areas around Blue Mountains Road, Sunbrae Drive, Whitemans Road, Pinehaven Road, Birch Grove, Pinehaven Reserve, and Chichester Drive, Upper Hutt.

By making the stream wider and deeper, the goal is to provide capacity in the stream for a 1 in 25-year return period flood event and to protect floor levels to a 1 in 100-year return period. So, property owners can expect the capacity of the stream to be five times greater than now and for flood water not to enter homes during 100-year weather events.

The project is just about to enter the detailed design phase. Prior to that we’ll be engaging with directly affected property owners to include everyone’s thoughts into our design thinking.

Pinehaven has a long history of regular flooding events, with 1976 being the largest; Whitemans Road bore the brunt of the floodwaters.
