Auckland Transport (AT) and the mayor's office confirmed no infringement notice wasissued and Brown has not owned up to the offence - unlike three weeks earlier when he was caught parking across a cycle lane, and handed himself in by referring the blunder to AT.
Witness Lloyd Kenny said the mayoral car pulled up at 3pm, Brown got out and the car was still there 10 minutes later when Mr Kenny's bus arrived.
Councillor Cameron Brewer said the mayor had escaped on a technicality because there was only photographic and not first-hand evidence.
But Brown's press secretary Glyn Jones said: "The mayor expects to be treated the same way as any other Aucklander and AT has been reminded of that. All council staff including the mayor's drivers have been reminded of the need to follow the road code."
