Weather: Auckland's west coast beaches off-limits as powerful storm whips up 'very dangerous' waves

Multiple warnings have been issued for Auckland's west coast beaches on Tuesday as a powerful Southern Ocean storm whips up deadly waves.

"The entire western side of New Zealand is a 'NO GO' for being in the sea for the next few days as very dangerous conditions move in," WeatherWatch warns.

"The West Coast will be most impacted by waves as high as 10 metres. Very dangerous waves of up to seven metres may impact the western North Island.

"Eastern areas are calmer - but remember strong winds will be blowing out to sea so if on floatable devices that increases your chances of getting into trouble. If in doubt, please stay out."
