Heavy rain warning for Canterbury

Cold and wet weather for much of the country, especially Canterbury, has prompted weekend warnings, and calls for drivers to take care.

Heavy rain is expected to continue to make its way down the country through Saturday, with a heavy rain warning for Tai Rāwhiti/Gisborne, and a heavy rain watch in place from Marlborough through to Canterbury.

Yesterday, the upper North Island was battered by heavy rain and strong winds. Overnight from Friday, MetService said the most significant falls were in the Wellington and Marlborough regions.

Rain warnings for Canterbury

A heavy rain warning is in place from early Saturday into early Sunday for areas north of Cheviot in Canterbury and into Marlborough. Snow was also expected, above 500 metres.

Heavy rain is also expected for Canterbury south of Cheviot, for Saturday afternoon into Sunday evening, particularly in the foothills and around Banks Peninsula. Snow in some areas was forecast above 500m.

That heavy rain could continue into Monday, MetService said.

Heavy falls could lead to slips which could close lanes, Waka Kotahi said.

Road snow and ice warnings were in place for the Lewis, Burkes, Arthur's and Porters Passes, from Saturday into Sunday.

A strong wind watch was in place for Marlborough, Nelson, Tasman, Buller and parts of Westland, into Saturday morning, with southeasterlies potentially approaching severe gales.

More heavy rain for Tai Rāwhiti/Gisborne and Hawke's Bay

MetService issued an orange heavy rain warning for Tairāwhiti/Gisborne, with up to 60 millimetres of rain expected overnight into early Saturday, on top of what had already fallen.

"Peak rates around 10mm per hour" could fall, "with the largest amounts likely about the ranges and north of Tolaga Bay", the warning said.

Heavy rain was also forecast for the Wairoa District and ranges of Hawke's Bay into Saturday morning.

Gisborne mayor Rehette Stoltz said it felt like the town had been "under attack" from the weather since January, after another night of heavy rain.

Tai Rāwhiti suffered extreme damage earlier in the year, with Cyclone Gabrielle and the Auckland Anniversary floods cutting off some rural communities.

Workers were still trying to restore the road networks, bridges and infrastructure, but could not keep up with the constant damage, Stoltz said.

So many warnings had been issued to locals in the past seven months, they were repeatedly being told to prepare for the worst and not being given the chance to recover, she said.

"We are absolutely being kicked while we are already down. We are a strong community, we have seen so much this year and every time as we try to get up and get into recovery it is one step forward, two steps back."
