Two cold fronts are set to move up the South Island during Friday then stall around central New Zealand on Saturday before moving away from Aotearoa during Sunday.
“These fronts are set to bring gale northwesterlies to the Canterbury High Country, eastern parts of the South Island and the Lower North Island during Friday," says MetService meteorologist Andy Best.
"Severe weather forecasters have issued several Severe Weather Warnings and Watches associated with this developing feature.
