Surf lifesaving clubs up and down the country are preparing for the first day of the season patrolling New Zealand beaches.
United North Piha Surf Lifesaving Club president Willy Goer said he was expecting a fairly quiet first day of the season.
"Conditions are quite dangerous. I think this weekend we're not expecting too many of the public out here, we'll have more lifeguards than people on the beach."
The sea had become rough due to the southwesterly winds and there were always rips, Mr Goer said.
Swells were about 1.5 metres and "fairly messy" with offshore winds, he said. "Not the best conditions."
