Prime Minister Bill English has taken yesterday's insults from Labour's deputy leader Kelvin Davis in his stride, but lay some reciprocal blows against Labour's policies saying "not much" would change.
Mr English was described as having the "personality of a rock" on TVNZ1's Q+A by newly elected Mr Davis.
"It was kind of flattering," Mr English said on TVNZ1's Breakfast this morning.
"I thought he'd move on not just from the rock but to the rock-star economy."
"So rock-star, that's me."
When asked by Breakfast presenter Hilary Barry if "Bill-fever' could match "Jacinda-fever", Mr English said: "I can never quite be the same. I'm not going to compete."
However Mr English said the Green Party would be the "most worried" about the popularity of Labour leader Jacinda Ardern.
"There's always a bit of enthusiasm about a new leader, the big issue though is the follow through."
He said Labour's policies indicated "not much is going to change".
Mr English said Labour's transport policy was the same as the last two elections, that National's social policy was "well ahead", and Labour's economic policy was "a bit hollow".
"When people are voting on the things that really matter to them, their jobs, their opportunities, what's happening with housing," Mr English said.
