New Zealand weather: Winds to create dangerous waves throughout the country this week

Wild weather that lashed the country overnight Sunday may have eased but forecasters are warning of strong winds creating dangerous waves throughout the country this week.

MetService issued a raft of severe weather warnings for Sunday evening and early Monday due to concerns about wind and rain.

On Monday morning, power authorities worked to restore power in parts of Auckland.

WeatherWatch says the strong south-west flow across New Zealand, and low pressure above the Tasman Sea at the weekend, has generated dangerous waves for western and southern parts of the country for Monday. A new surge would come over southern parts late Wednesday and through Thursday.

"The wave heights in the west will be 6 to 8 metres during Monday afternoon, incredibly dangerous for small vessels," a statement said.

"People should also avoid fishing on rocky western areas, like Auckland's west coast, until conditions ease."

Severe warnings remain in place for the Westland ranges - south of Otira and Fiordland.

"This week should be noticeably cooler with what is normally expected in May," meteorologist Stephen Glassey said.

MetService says southwest winds peaked at 31kmh at 4am Monday.

"As the low moves to the east tomorrow [Monday] it will bring a period of strong cooler southwesterlies to many places," MetService says.

"However, westerlies develop over much of New Zealand on Tuesday as a front starts moving north over western areas."

Glassey said the cool weather would likely dominate the country this week.
