Sharks have been spotted at a popular west Auckland surf beach.
An alert has been posted on Auckland Council's Safeswim website on Saturday afternoon advising against swimming at Muriwai Beach.
Sharks have been sighted at a number of beaches around Auckland over the last few weeks, on both the west and east coasts.
A 19-year-old woman died in a suspected shark attack at Waihi Beach early last month.
The last fatal shark attack in New Zealand waters before that was in 2013, at Muriwai Beach.
