Shark sightings at beaches to rise in summer

An expert says a large shark filmed off a popular swimming beach near Nelson was probably a great white — and it should come as no surprise to anyone.

Last weekend, a large shark was spotted near Rabbit Island on Nelson’s coastline.

Based on the creature’s behaviour and shape in video footage, Department of Conservation marine scientist Clinton Duffy believed it was a great white shark.

Duffy claimed sharks were performing their seasonal migration en masse from the tropics to New Zealand about now, and could be found off most parts of the country.

Although our rarest large shark, great whites were seen regularly in the upper North Island throughout the year but as summer approached, they would become more abundant further south.

There were ways people could keep safe if they encountered a shark in the water, he said.

“The most important thing to do if you see a great white shark is stay calm. If you’re in the water, obviously you’re going to get out of the water as quickly and as quietly as possible.

“If you’re scuba diving, you should stay on the bottom, keep an eye on the animal and don’t attempt to leave the water until it has moved away.

“Leaving the water, you’re best to do that either [by] surfacing directly underneath the boat that you’re from, or swimming along the bottom and getting out on the shore or on a nearby rock.”

It was typical for white sharks to investigate any “novel object” they came across in their environment, by swimming up, looking at them and biting them “to see what they are”, he said.

However, there were also many interactions with divers that did not result in attacks.

Duffy said people should treat any shark over 1.8m long as potentially dangerous, but most sharks were “no trouble at all” and with summer approaching they expected to see more bronze whalers and hammerheads close to the shore.

DoC is asking for any sighting of great whites or other protected marine species to be reported to their hotline, 0800 DOCHOT (0800 362 468).
