A diving trip off Kaikoura yields some good-sized specimens.
Crayfish and food. That is what springs to mind when the word Kaikoura is mentioned and the translation kicks in. So when Anton Evans offers to take us out in his 9m charter boat, the Rodfather, to pick up crays we don't hesitate.
"We'll pick up some crays for you to take home, and then I'll bait the pots," says Evans as he backs the boat down the slipway at Kaikoura. Giant cray boats are parked alongside charter boats on huge trailers. Double-wheeled tractors haul them in and out of the sea, and just across the harbour five large cats sit alongside the jetties, waiting to carry tourists out to the deep canyons where the sperm whales roam.
It is 2km deep just off the coast and the whales dive down to a 1km, staying down for 90 minutes as they hunt fish like groper and squid. The sperm whale grows to 20m and consumes up to a tonne of food every day.
Anton dropped the anchor in only 5m of water and with his diving mate from Christchurch, Grant Silvester, planned to swim against the current and the wind as they hunted crays on a sloping shelf where the reef dropped away.
