Heavy Rain - Flooding Updates

3pm Wednesday 2 June

The flood gate at The Pines Beach and Kairaki has been operating well and the advice from Environment Canterbury is that the water is receding. This means that there is no longer a risk and the prepare to evacuate warning has been lifted for The Pines Beach and Kairaki.

A temporary speed limit is in place on Beach Road near the culvert, as the pump hose is across the road. Residents should take care driving through this area.

Civil Defence, the Mayor, and Council staff had a meeting with the affected families at Okuku last night and continue to provide advice and support to them.

Lees Valley Road to the south and Okuku Pass Road to the north are inaccessible due to road damage caused by significant flooding. The Council continues to support these communities and will be carrying out an engineering assessment by helicopter this afternoon.

We are continuing welfare checks with people we know that have been directly impacted. If you know of any residents who would benefit from a welfare check-in please call 0800 965 468 and ask to speak to one of the team.

The Garrymere water supply is experiencing higher than expected turbidity (cloudiness) levels, which means the treatment system may no longer be able to sufficiently treat the water.

As a precaution, residents on the Garrymere water supply need to use boiled water or store-bought bottled water for drinking, cleaning teeth, making ice, washing dishes and preparing food until further notice.

Forecast low temperatures over the next few nights may result in icy road surfaces meaning extra care is required, particularly as many roads have been flooded and there may still be some debris around so please take care. Often it is hard to see patches of water on the road until it is too late.  Even less visible is black ice. Slow down and please don’t attempt to drive through flooded roads or fords where you can’t see the road surface as there may be damage to the road surface that you can’t see.

Areas currently impacted

  • Six properties in Okuku
  • Less Valley

Looking after each other

It’s important to recognise that this is a stressful time for many people and that we may react to situations in very different ways. The impact of the flooding may continue for a number of days or weeks and there is support in place. So if you find yourself or your family or friends need to reach out you can find a range of local support services here

Advice from Insurance Council of New Zealand

Insurers request people not to throw things into skip bins until they have been instructed by their insurance company that it is OK to do so as they will require proof of loss.  If the property to be discarded is considered a health hazard then photos can suffice but it pays to check first.  The message for homeowners is to please talk to your insurer before discarding any items and they will talk you through their process.  Take photos of any items you are taking out of the house for sanitary reasons such as soft furnishings or carpet.

Water schemes

We will send another message when normal use can resume.
