There's a joke that goes something like this.
A judge is sentencing a wood pigeon poacher.
"I am curious, I have to ask" says the judge. "What do wood pigeons taste like?"
"They taste a bit like kiwi, your honour".
Sonny Tau has found himself in a hot water - he's not accused of poaching but it seems he was caught in possession of several kereru - protected wood pigeons.
