Auckland Mayor Wayne Brown refuses to resign, promises investigation into Friday's disaster response

Auckland Mayor Wayne Brown has promised a full investigation into Friday's response to the worst rain event in Auckland's history.

The under-fire mayor says the review will include looking at the communications from himself and his office.

Wayne Brown - front and centre, and defiant as ever.

"I'm certainly not going to resign. I was elected to fix Auckland and this is a giant fix-up," he said.

Even in the midst of a historic flood, the Auckland Mayor himself has become a major talking point.

"I'm calling for his resignation, he's not up to the job. He's out of his depth and it's nothing personal," said community leader Dave Letele.

Some say Brown should walk his own talk.

"What I said to him was you called, in your campaign, for a lot of resignations out of frustration and I'm just doing the same," Letele said.

Some council colleagues were not exactly full of praise for Friday's response.

"I guess the timings of communications will come in time, right now we're focused on cleaning up," Councillor Richard Hills said.

"There's a lot that needs to be reviewed about even the state of emergency declaration," added Councillor Josephine Bartley.

Despite a petition calling for change approaching 15,000 signatures, the Mayor insists he's going nowhere. But on Tuesday he did strike a more conciliatory tone.

"I accept that our communications, including mine and my office, were not good enough, especially on Friday night," he said at a press conference.

It was a very obvious change in strategy from Saturday. And some colleagues say he has been doing the hard yards since the chaos of Friday.

"He was here and that was good, he came back a second time to tell me about some advocacy he is doing," Manukau Councillor Alf Filipaina said.

While others went into bat on CNN.

"The emergency service met, they talk about a State of Emergency that was left until about 8:45pm and within eight minutes the state of emergency was called," Auckland Deputy Mayor Desley Simpson said.

As the man in charge refuses to bow to the pressure, focused on an almighty clean-up for now and how Auckland's going to cope with a changing climate in the future.
