The death of an 89-year-old local woman at Mangonui on Tuesday evening has been referred to the coroner.
A police spokesman said Anthea Goodwin and her nephew had left a restaurant on the waterfront about 7.30pm.
She crossed the road to the harbour edge, just south of the point where the Neva Clarke McKenna Boardwalk ends, to look at the fish she could hear splashing in the water.
Her nephew, who had had to wait for a car to pass before he could cross the road, found her moments later where she had fallen, into about 45cm of water. He managed to get her on to rocks before going for help, but attempts to revive her were unsuccessful.
The police spokesman said Goodwin had not been well for some days, and it was possible that she had suffered a medical event before she fell.
