Rain has been falling in Hawke's Bay and Tai Rāwhiti and more is forecast just as locals pick up the pieces from Cyclone Gabrielle.

A front has been moving up the country, with the Marlborough, Nelson, Wellington and Wairarapa regions getting up to 50mm of rain overnight.

Hawke's Bay and Gisborne had about 15mm over the same period and could be in for another dousing later in the week.

MetService meteorologist Allan Baillie says the most recent modelling shows that in the 24 hours to Saturday morning 150mm to 200mm of rain could fall in the Hawke's Bay ranges, which would be very concerning for the region.

Gisborne could get up to 120mm over that period, and Wairarapa is also under a heavy rain warning.

As of Wednesday afternoon, 346 people remained listed as uncontactable in flood-affected areas.

Police have deployed four specialist victim recovery dog teams to the Eastern District to help in the search.

The death toll remains at 11 - nine people in Hawke's Bay, and two firefighters in Auckland.

About 700 people displaced by Cyclone Gabrielle across the North Island are still seeking shelter at Civil Defence centres.
