Waka Kotahi has advised there will be work tonight to repair the crash barrier at the corner of State Highway 59 and Pukerua Beach Road (map). The work is being done at night when there are fewer vehicles so it can complete the job quickly, efficiently and safely without causing major traffic delays.
Waka Kotahi have advised the following:
Good afternoon,Anita De Klerk, Customer Communications and Engagement Advisor
Due to the weather the daytime stop/go for road repairs on Coast Road, between Pukerua Bay and Paekākāriki has been moved to Thursday 28 July and Friday 29 July.
We are keeping an eye on the weather and will let you know if these dates change.

Do you live in Pukerua Bay or Whitby? 🤔
We’re working hard to reduce the risk of flooding and keep our communities safe, now and into the future, but we need your help! 🙋♀️
💧 Does your garden fill up with water when it rains?
💧 What about your street?
💧 Your local school?
Currently, Wellington Water is mapping areas in Porirua which we suspect are prone to flooding in heavy rainfall events. 🌧
To ensure these flood hazard maps are as accurate as possible, we need you to tell us about your flooding experiences in Pukerua Bay and Whitby. 🧑💻

Weather pemitting Porirua Council’s Contractor will be carrying out berm spraying in two areas of Pukerua Bay. The work should be completed on Friday but may spill over to Saturday.
Area 1: From Sea Vista Road to 55 Muri Road
Area 2: Coroglen Rise from Airlie Road to the end

PCC have just advised that it will be closing Pukerua Beach Road between 9am and 1pm tomorrow (Wednesday).
There will be emergency access, however residents are urged to find alternate access options or to remain at home during this time.
Given the narrow nature of Pukerua Beach Road, a full closure is required to carry out work to construct a bund on the coastal side of the road to prevent water going down the bank. This is one of the actions recommended by geotechnical advisors ENGEO.
Claire Giblin will be writing a fuller community update, which will sent out later today but wanted to alert residents to the closure as soon as possible.
PCC apologises for the inconvenience.
Latest reports from PCC re the Pukerua Beach Road situation.
Council has a geologist on site at the moment and PCC will give updates. Its all just precautionary at this point. Its been challenging weather across the whole city this weekend. There have just been reports of some cracks on Pukerua Beach Rd so they are assessing that currently and any slip risks to Ocean Parade.
There are numerous crews out this way assessing the conditions. and a few PCC staff on the ground speaking to the residents who may be impacted. PCC wanted to reassure residents that Downer will be on site all night and PCC Emergency staff are also here should anyone need support with finding alternative accommodation (should any areas be deemed unsafe – which has not been confirmed). PCC will send an update when there more info from the crew on the ground.
I have just had a call from Claire Giblin (PCC). The latest period of rain has been causing more slips on Pukerua Beach Road, closing it. Downers are working on clearing the road.
And it appears that there have been slips on Cluny Road (Karehana Bay) with some residents evacuated from their homes.
This email is intended to update you on our progress with the investigation around the slips on Pukerua Bay Beach Road.
Our thanks to the residents who have worked with the Council and geotechnical specialists ENGEO to share their knowledge, and allow us access to their properties.
We received ENGEO’s latest report yesterday. We will make it available once we’ve had time to review it and are able to confirm our preferred options. We are looking at several stability options with ENGEO and will need to align them with available funding.
We appreciate you are keen to see some action and we ask you to be patient so we can fully understand the cause of the slips and plan accordingly.
Our maintenance contractor Downer continues to monitor the road during heavy rain, and clear rock falls, as it did last weekend.
ENGEO has good local knowledge of the area and underlying issues having been involved with investigations into the following slips:
• 6 Ocean Parade (November 2016).
• 7A Haunui Way (2017 – 2018).
• 41 Haunui Road (October 2018).
• 57 Haunui Road (November 2020).
• 47 Haunui Road (December 2020).
• 19 Ocean Parade (March to August 2021).
• 1 Ocean Parade (8 December 2021).
The two (2) crib walls on Pukerua Beach Road are a separate matter to the slips but will also be investigated (to come).
Wellington Water recently undertook a leak detection survey of the water pipes in the area above Pukerua Beach Road:
• Two (2) minor leaks were discovered.
• To the best of their knowledge there are no stormwater pipes in the area.
• Residents’ stormwater is discharged to the ground via soakage pits.
• The likelihood that a leaky potable and/or stormwater pipe is contributing to the groundwater concerns in the area is very unlikely.
• An assessment of potential leaks from sewerage pipes is ongoing.
The common theme in all these slips is that they appear to be the result of erosion from water flow of both surface water and groundwater. It is understood that many, if not all, of the stormwater drains from the properties along Haunui Way and Haunui Road discharge directly to the ground, and this combined with natural infiltration of surface water through highly permeable surface soils, is the likely main reason for high groundwater flows in the area.
Rest assured remedial actions are in the planning phase and will be programmed accordingly (especially external funding).
We will continue to keep in touch as our investigations continue, and welcome your feedback.
There have been some further rockfalls around te slip on Pukerua Beach Road. PCC will be monitoring the area while the weather continues on its current phase and will take action as and if necessary.
