New Zealand civil defence staff have sent out text alerts to residents in North and West Auckland today to avoid unecessary travel as thunderstorms brought localised downpours.

Those in Rodney, Helensville, Upper Harbour, Te Atatu and Henderson Valley received an emergency alert on their mobiles this evening as the rain has increased the risk of landsliding and flooding.

Bethells Beach, Piha, Karekare and Muriwai, which have been cut off since Cyclone Gabrielle, have also received the the mobile alert.

Areas north of Auckland were hit by the sudden torrential downpour this afternoon causing slips, road closures and surface flooding in towns including Mangawhai, Wellsford and Te Arai.

The intersection of State Highway 1 and Mangawhai Road is closed, say police.

Motorists are able to continue north on State Highway 1, but cannot access Mangawhai Road.

Police said there were slips in north-west Auckland, especially in Mangawhai.

Meanwhile, heavy rain warnings remained in place for Hawke’s Bay, Gisborne and the Coromandel — all regions devastated by last week’s cyclone — as they braced for more downpours this weekend.

Metservice said the heaviest rain for Hawke’s Bay would be during Saturday morning with the risk of thunderstorms.

An evacuation order has been issued for people in the Esk Valley ahead of the heavy rain. It took effect from 1.30pm today.
