Swimmers are being told to steer clear of several local beaches after multiple sharks were spotted.

Auckland Council website Safeswim notified users that Omaha Beach, Tawharanui Beach and Anchor Bay all had shark sightings.

Safeswim has issued a "swimming not advised" notice for Omaha, and is urging people at Tawharanui and Anchor Bay to exercise caution.

The warning for Omaha was put in place at 3:24 p.m. on Tuesday the 28th.

Omaha beach is patrolled by Surf Lifesaving teams, but neighbouring beaches Tawaharanui and Anchor Bay are not. It is advised to enter the water at your own risk.
