"The rain will likely fall as snow above about 900 metres over the South Island, which may affect some alpine passes," MetService says. "The low should weaken over the South Island on Thursday, while a disturbed westerly flow covers the North Island."
Boaties can expect choppy seas with large combined waves in the next few days as the strong wind kicks in. It could make for hazardous conditions on the water, MetService warned this weekend.
It's a wet and windy start to the week across the top of the North Island.

Civil Defence controller Garry Towler urged residents not to take risks with unnecessary travel.
"Our catchments will struggle to cope resulting in surface flooding, slips, isolation and maybe power outages.
"This event is an ex-tropical front packed with a lot of rain, so get prepared once again at home and work, stock up on essentials and plan for delays, isolation and flooding in low lying areas."
