A Tauranga man who has experienced some of the rarest encounters with marine life will be sharing those moments and providing tips on how others can do likewise next week.
Nathan Pettigrew is a marine mammal permit holder, which gives him the ability to get as close to nature as possible. His footage from such encounters has earned him a worldwide following on social media, and the chance to share conservation messages.
On Thursday, Pettigrew will host an evening at Toi Ohomai Institute of Technology as part of Seaweek, which begins today.
Pettigrew has previously held talks at local primary schools but this will be his first to an adult audience. Pettigrew will cover his background, how he got into photography, holding a permit and some of his incredible encounters, plus reminders of Department of Conservation (DoC) rules regarding marine life.
"There will be pockets of information here and there but really, it's going to be around the marine life," he said.
Seals, dolphins, sharks, whales, orca, manta rays and even a sunfish are among the creatures Pettigrew has encountered and filmed - all in Tauranga waters.
Pettigrew admitted he still struggled every time he shared such footage and had recently slowed down in doing so.
"I really worry that if I put it out, 'is this doing any good?'. Every time I go to do it, I think 'don't do it' just because people look at what I do and they want to do it."
Pettigrew is the only non-commercial and non-research person that he knows of to hold such a marine mammal permit in New Zealand. Getting close to some marine life without one is an offence and, in cases involving leopard seals or whales, dangerous.
But Pettigrew has been heartened to know his messages of "how we interact with marine mammals and what we can do to look after them" are being heard.
"A lot more people know that there are rules now. I was with a pod of orca in 2015 and there were people everywhere and DoC didn't get any complaints. A year later I was with a pod of dolphins again, same scenario, and DoC got seven complaints. That shows it's working, but there's still a lot of people that really need to slow down around them."
Pettigrew said Tauranga Harbour was teeming with marine life, which could be easily be spotted if you knew where to look. He would offer his tips to help people see what they could, without breaking any rules.
