Bill Kerrison is helping save our native longfin eels or tuna. Each year he traps and transfers eels and other native fish species past a series of dams on the Rangitaiki River in the Bay of Plenty, so they can continue maturing or head out to sea to breed. Spectrum's Lisa Thompson meets the man locals have nicknamed 'Mr Tuna'.
"My priority right from day one was water. Because if we haven't got good water, where's our next two generations from my children, and their children and their children, gonna be?" - Bill Kerrison
Bill Kerrison has lived near water - salt and fresh - his whole life. And despite stints mining, farming and in forestry, he's always managed to find his way back his life source. Much like his beloved tuna, or native longfin eels.
While these sleek, black giants have a reputation for lurking in the murky depths of our waterways, Bill Kerrison regards them as one of the most intelligent species of fish on the planet and has a deep connection with what he affectionately calls his beauties.
A connection that started way back in the 1940s in Thames, when as a young boy, he befriended a sinewy mass of eels that lived under the local jetty.
He was put to work on his father's mullet boat but when a storm left her a wreck, the family packed their bags and moved further up the Coromandel Peninsula to go shearing.
"I loved it, I loved it, it was right in my environment," says Bill. "But I ended up running away from home...people have their fights...and of course alcohol is a big distribution to that...I knew I had to go."
So at 14 and a half, Bill hitched a ride across the Hauraki Plains to his older brother's house near Rotowaro in the Waikato.
"That was it, I was underground just after I was 15 and stayed underground until I got called up into the armed services...that was the beginning of my man's life then."
After the army, Bill spent time in freezing works and as an engineer, before finally coming to Edgecumbe to run a fish and chip shop. It was here that he met his second wife Ruby, whom he affectionately calls 'mum'.
After the 1987 Edgecumbe earthquake Bill and Ruby moved inland to farm at Galatea. And while it's 70 kilometres from the coast, water was once again close by.
Behind the Kerrison's property flows the mighty Rangitaiki River, the longest in the Bay of Plenty, 155 kilometres in length. Once free-flowing, the river is now damned for hydroelectricity. And it was on the banks of the Aniwhenua dam that Bill's life took a significant turn in 1991, when he came face-to-face with his beloved long-fin eels again…
