A severe weather watch is in place for parts of coastal Hawke's Bay, Fiordland and South Westland.
Heavy rain and southwest gales were expected in coastal and northern Hawke's Bay tonight and tomorrow morning.
The heaviest falls were expected about the coast south of Cape Kidnappers, and eastern parts of the Wairoa District, the Metservice said.
While overall rainfall might not be severe, there was the chance of heavy rain in localised areas in the hill country east of Wairoa.
Southwest gales were also likely about eastern parts of the Wairoa District.
The weather was expected to ease late Saturday morning.
Fiordland and Westland south of the glaciers are likely to get periods of heavy, thundery rain from Saturday afternoon through to midday Sunday, which might be severe.
