Sharks have been spotted at Auckland's Eastern Beach, just a day after some were sighted at Muriwai Beach on the region's west coast.
On Sunday morning, an alert posted on Auckland Council's Safeswim website advised Eastern Beach swimmers to exercise caution due to sharks being sighted.
Sharks were also seen at Muriwai, a popular west Auckland surf beach, on Saturday and an alert remains in place on Sunday morning.
There have been reports of shark sightings on both east and west coast beaches in recent weeks.
Last month, a woman was killed in a suspected shark attack at Waihi Beach, a coastal community in the Bay of Plenty.
