Two mass rescues, each of more than a dozen people caught in rips, took place at northern beaches on their first hot Saturday of the season.
Surf Life Saving's Northern Region, which covers Auckland, Northland and Raglan, said 46 people were rescued across its beaches .
One of the mass rescues was at Auckland's Muriwai, and involved 13 people being brought back to shore.
They got into strife when a couple of rips suddenly opened up while several hundred swimmers were in the water.
