Friends Charlie Cartwright, Aaron Fell and Joseph Wilson had a quick dip, but didn't want to go deeper than chest-height because of the news of the shark.
"We thought because the waves were stirring up water the shark wouldn't want to come in that close ... but we're just guessing," Mr Cartwright said.
"I was looking for sharks the whole time," Mr Fell added.
A group of Henderson Intermediate students, some of them eagerly chatting about the shark attack, were on a school trip at the beach today, but would only be swimming in the safety of the lagoon.
Elise Henry, 12, said she would be reluctant to swim in the sea at the moment because of what had happened.
"If they actually knew that there were no sharks around here, then yes, I would - in the safe areas."
Kent Hyland said he was more concerned about rips than sharks.
"You only go out so far anyway. Sharks don't come into the beach, eh."
At nearby Piha, dozens of people took to the water today.
"There's really no point in worrying about sharks. If you're rational about it, there's a far greater chance you'll drown, or be killed by a car on the way to the beach," said beachgoer Tim Harding.
"I think it's purely psychological. I remember when the film Jaws came out, I was terrified of sharks - everyone was terrified of sharks - but that's not the reality of the situation at all. Generally they'll keep out of people's way.
"I'd be lying if I said I wasn't looking for shadows in the water when I was swimming, though."
Natalie Stettler said she has always been afraid of sharks, and was no more afraid now.
"I'm from Canada and it's the same there with grizzly bears. People go into their habitat and they're surprised when they're attacked. I think you just have to respect them."
Graham Spence said he saw a fin, which he thought was a shark's, when he was fishing at Muriwai about two weeks ago.
"They're out there, alright," he said.
"Let's not get too worried about it. It's just so bloody sad that someone was killed."
