A man walking his dogs came across a shark rolling in the surf this morning, near where five sharks were seen yesterday on the Kapiti Coast.
Matt Gibbins was this morning at Te Horo Beach, 69km northwest of Wellington and the next beach over from Peka Peka Beach where yesterday's sharks were seen.
"I came across this dead 2m bronze whaler rolling in the surf at Te Horo Beach, one of the five spotted yesterday perhaps?" Mr Gibbons asked.
Yesterday's sharks were also seen at Waikanae Beach by a Heliworx helicopter working in the area.
The helicopter initially spotted two sharks but then saw five, a Central police spokesman said.
Kapiti Heliworx chief executive Dennis Young was flying along the coast at about 2.30pm, when he spotted the five sharks between the two beaches.
Some of the sharks were spotted again in the water off Peka Peka, between 3.30 and 4pm.
Local Nick Kortens read online about what was happening and headed to the beach.
"I went down with a pair of binoculars and I spotted a few fins 300 to 500m offshore.
"You generally don't see them off Peka Peka. We've had great whites before," he said.
Mr Kortens lent his binoculars to German tourists and they had a look too.
"They were quite impressed, they hadn't gone into the water."
Mr Kortens was a regular beachgoer and would often enter the surf. Yesterday, however, he had stayed out, he said.
Mr Young said what alerted him to the sharks was a sand trail.
"They were in so close they were kicking up sand with their tails. We could see this long, dirty sand trail and right at the end of the sand trail is where the sharks were."
He thinks the sharks were bronze whalers, about 2m to 3m long. They were between 50 and 75m off the shore and possibly looking for stingrays, which had been plentiful in the area.
Mr Young landed his chopper on the beach and got two groups of two swimmers out of the water.
"We landed and gave them a bit of a heads-up of what's going on."
One swimmer didn't understand English, but knew what "shark" meant.
"The look on their faces was quite priceless really."
Mr Young has flown in the area for a few years but never seen sharks before. He had previously spotted whales, and yesterday morning saw dolphins.
The Sand Castle motel is on Waikanae's beach front and owners Des and Narie Geffney heard Mr Young's helicopter come in to land.
"We wondered what it was," Mr Geffney said.
"We could hear him hastily coming in to see what was what. We could just hear it in our lounge."
He and his wife didn't see the sharks.
Amy Edwards took her 11-year-old daughter and two other children, 10 and 8, to Peka Peka for a swim yesterday afternoon, only to be told by another beachgoer there were sharks in the area.
"I'm grateful they told us. I was going to send the kids out into the water and let them go for it."
Ms Edwards wondered why there were no signs warning of the sightings.
"Lots of people came down after us that didn't know either."
Today, the three children stuck to the shallow water, but thought the whole situation was quite exciting.
Department of Conservation marine scientist Clinton Duffy said bronze whalers lived mainly around the upper North Island at this time of year.
"It's rare to see them as far south as Cook Strait, but they have been recorded there before.
"They are not usually a risk to swimmers, despite their rather large size. They feed mainly on fish."
Mr Duffy said they'd been known to become aggressive toward spear fishers from time to time.
It wasn't unusual to see them in shallow water and they're often found in water less than a metre deep.
Occasionally they'd made their way to Wellington Harbour and Tasman Bay, across the strait.
Mako and blue sharks would spend time in the area, around Kapiti Island.
Blue sharks sometimes made their way into shallow water too Mr Duffy said.
According to Te Ara Encyclopedia of New Zealand, there were 11 fatal and 37 non-fatal shark attacks in New Zealand to 2014. Since a death in 1976 at Te Kaha, the only fatal attack was in 2013 at Muriwai on Auckland's west coast where Adam Strange, 46, was killed by what's believed to have been a great white shark.
At the time a witness told the Herald he saw a "huge" shark attack a man swimming alone.
