Wasp warning: Ruakākā Beach walker warns public after being stung 50 times:

A Northland woman is warning people to be wary of wasps after she was stung about 50 times during an “utterly frightening” attack.

Elke Radewald had been walking with her dog along the Ruakākā Beach path near the end of Bream Bay Drive about 11am on July 21 when she heard a buzzing noise behind her.

“I turned around and there is this big black ball coming towards me. It was like in a really bad movie,” she said.
