Fine weather has lured people in Auckland to dip into the water at the beaches despite public heath warnings urging them not to.
Warnings are in place telling people not to swim, take children, dogs or eat seafood from beaches on the city's eastern shores and the Hauraki Gulf after the mysterious death of dogs and sealife.
Signs at Cheltenam beach, where one of the dogs had been for a walk before it died, have gone unheeded.
Daniel Romero, one of a handful of people who went kite surfing at the beach yesterday, says he was aware of the warnings, but the wind and good weather were just "too tempting".
Test results of samples from the water and beaches are expected next week.
