Mr Guy demonstrated by grabbing hold of it with the full hand, rather than lightly touching it with one finger.
Mr Guy even demonstrated for him, holding on to the wire and saying, "I can't feel it much at all now," as he urged Mr Key to give it a go.
But it was one step too far, even for photo-op-friendly Mr Key. He opted to follow the cows' advice over his minister's and steered clear of the fence. He conceded he was all gumboots and no cow, saying he knew about economics, not farming. However, watching Mr Guy clutching the fence, Mr Key wondered what message it might send about the average IQ of the National Government to have ministers grabbing electric fences willy nilly.
"I just want to apologise to the New Zealand public," he said, laughing. "This is all I've got to work with."
Mr Key wrapped up his visit at a barbecue by saying the farm and surrounding area felt so much like New Zealand that "I feel like I'm at a National Party fundraiser."
