Swimmers at Ōmanu Beach were ordered out after a 2m shark was spotted nearby.

Safeswim issued a safety warning around 3.30pm advising against swimming due to the shark sighting.

The beach was closed for half an hour before being reopened by Surf Lifesaving teams.

Swimmers at a Tauranga Beach were ordered out of the water this afternoon when a 2m long shark was spotted swimming within 50m of the shore.

Safeswim issued a safety warning for Ōmanu Beach around 3.30pm advising people not to swim because of shark sightings.

An Ōmanu Beach Surf Life Saving Club lifeguard told the Herald the shark was first spotted about 100m to the right of the beach.

He said the club’s roaming patrol staff followed it as it swam through the flags and then told the tower crew, who then sighted it.

“We closed the beach, got everyone out of the water and then waited half an hour before we reopened everything.”

The Surf Lifesaving team has now reopened the beach.

It is the latest in a series of shark sightings on New Zealand beaches this summer.

Safeswim issued a safety warning for Whiritoa Beach on December 27, advising people not to swim because of shark sightings.

A spokesman for the Whiritoa Lifeguard Service told the Herald there had been three separate shark sightings close to the shore and the beach had been closed intermittently.

A 2m shark was spotted in the shallows of Ōhope Beach on the same day.

Chris Service was in the water with friends, teaching his kids to surf, when a large shark swam right between them.

“My mates freaked out, his kid practically ran on water to get out,” Service told the Herald.

Not wanting to panic his kids, Service slowly walked to shore with them before telling them about the shark once they were on land.

Service then put his drone up to see if he could find the shark.

“Sure enough, as soon as I got it up, within a minute there it was, cruising right in the shallows with heaps of people,” he said.

“There were 50-odd people in the water ... Everyone got out of the water after that!”
