Armed with rods and life jackets, they spend hours at a time on the wharf keen to snare anything that's moving in the water of the estuary.
"We fish for anything that swims but only keep fish for the cat or bait," says Evans.
"If we do keep and eat any fish it'll be kahawai.
"We release anything that's not needed because I am trying to teach the boys about sustainability and looking after the marine environment."
He says fishing also gives him a chance to teach the boys practical skills, such as tying knots and filleting fish.
And it provides much cherished family time away from technology and screens.
"We get to enjoy a little piece of paradise that New Zealand has to offer."
He says fishing is a great challenge for the boys.
Fortunately, the estuary's water is flush with a variety of fish, kahawai in particular.
One of the trio's favourite dishes is raw kahawai cut wafer-thin, sashimi-style, with wasabi and soy sauce.
This is by far their favourite meal - ahead of fast food, Evans says.
All his boys use rods and reels but he reveals they have a secret bait - secret until now, at least.
"They catch shrimps in a small net around the pylons and then use the live shrimp as bait."
They also use pipi. Gathering the shellfish at low tide is another adventure tied into their fishing experience, says their dad.
The boys, who live in Auckland, love the pace of life on the peninsula and would rather spend their days fishing off the wharf than return to the city.
"The good thing is down there they always catch something. There is a good supply of fish and they are always successful."
