Flooding is likely to ease over the coming hours as the tide recedes but the next high tide will bring fresh flooding in parts of Christchurch.

Christchurch City Council Acting Head of Three Waters and Waste Tim Drennan said “most of the flooding that we’ve had so far has been related to the king tide.”

“High tide for this morning has passed and we expect to see the flooding situation ease. However, with the next high tide due at 8pm we expect to see flooding occurring again. If people have vehicles parked in areas affected by flooding this morning, we advise they move them this afternoon before the next high tide.”

“The flooding we have seen in other areas of the city has been caused by leaves blocking grates. We have contractors working to clear as many of these blockages as possible. But, if you are in position to clear any blockages near your property, we would really appreciate your assistance because we won’t be able to get everywhere.’’

Up to 8am this morning, Christchurch and the Port Hills have received between 40 and 60mm of rain. Parts of Banks Peninsula have received close to 100mm.

Rain is expected to continue falling throughout today and tomorrow.

“Most of the roads that we have closed this morning due to flooding are likely to remain closed until the high tides have passed tomorrow so if you normally travel these routes to get to work or school, please start thinking about alternative ways of travel.’’

High tide on Monday morning is due at 8.30am.

“If anyone living close to a river or waterway is feeling at all unsafe, please self-evacuate. If people want to report problems in their area, please call our Contact Centre on 941-8999,’’ Mr Drennan says.

“Our crews are working to ensure our stormwater network is working effectively as possible and are actively managing the outfalls at Sumner and Southshore to minimise any flooding.’’
