That drew a response from Brownlee, who said he deeply resented the comments and was "pissed off" that Murray had taken that attitude.
Today, Brownlee said he had a cup of tea and shook hands with Murray after the exchange, which was "just a moment in what was otherwise a pretty constructive meeting".
"I was fairly forthright. But I would also say that a lot of people at the meeting wanted to indicate that they didn't necessarily share all his views."
Brownlee said it would be unusual for people affected by the earthquake recovery not to be frustrated, and some had views about how things could be done faster.
"But from a Government perspective we've got to make sure that what is done is going to endure, and it can be done safely. And I think John standing up there and saying 'nothing is being done', I found extremely disrespectful.
"It is four weeks since the event, and the amount of work that has gone in to trying to create a good approach to recovery and meet people's needs as quickly as possible, has been quite extraordinary. I couldn't stand there and have him saying that NZTA and other agencies have done nothing. I couldn't do that."
Last month the NZ Association of Scientists said they were concerned that Brownlee had criticised GeoNet director Ken Gledhill, who had blogged about the need for an expanded earthquake monitoring system.
When Gledhill repeated the comments at a press conference, Brownlee said he felt blindsided by the scientist's comments.
