The most common shark people would see in the North Island and Upper South Island was the bronze whaler, Elliott said.
Further south, they could encounter the sevengill shark and the great white shark.
Sharks predominantly did their own thing, but to reduce being appealing to a shark, he recommended avoiding swimming in areas where people were fishing. Likewise, fishers should not discard their filleted fish parts in areas where people would swim, Elliott said.
Sharks like the bronze whaler also loved fish and were drawn to areas where people went fishing.
People needed to remember that when they were in the sea, they were in a wild environment with wild animals, he said.
“We should remember that it is their supermarket that we are venturing into.”
The deadliest of the sharks was the great white, but Elliott said they usually posed the biggest risk to surfers.
“That’s usually aligned with the fact that surfers dress up like seals wearing wetsuits and surf around where seals aggregate.”
But that was a very small portion of the population and most surfers understood that risk, he said.
The risk of a shark attack was tiny compared to the risk of drowning, he said.
