It was clear the Government had to get some consents in place to avoid a repeat of last Friday night, he said.
"I rang the Mayor of Auckland myself when it became clear to me yesterday after I made my media comments he hadn't been fully cited, and frankly I was surprised he hadn't been," he said.
In announcing the Government's takeover yesterday, Mr McCully said the ball had been dropped and the Government needed to step in to fix the situation.
Mr Brown told TV3`s Campbell Live last night that Auckland City and the Government "share equal responsibility for the glory and the grief."
He said that included Friday night.
He denied Auckland City was working unilaterally prior to Friday, and said everything the council had done was in collaboration with the Government and with the Government's full knowledge of what was going on.
Meanwhile a former Auckland City mayor says the Auckland Council made too many false promises to the Government over its delivery of Rugby World Cup waterfront ceremony and were lucky it didn't end "in a massive riot".
John Banks told Newstalk ZB the Government had swallowed the Council's plan "hook, line and sinker", and paid the price.
"It's an evitable consequence of planning and a gun-ho approach," Mr Banks said.
"The Govt can't afford to have another botch-up down there."
He said a single fanzone on the waterfront was never going to work.
"I think we were very lucky it didn't turn into a massive riot.
"There was enough drunken louts down there to trigger the biggest riot this country has ever seen.
"We have got away with this very lightly."
