Phil Goff has launched his re-election campaign today and has made Auckland's environment and climate change key priorities for his second term as he also took a swipe at John Tamihere.
Mr Goff is set to make council plans to only purchase electric or hybrid cars from next year with cleaner transport high on his agenda .
He is also hoping for government support in switching to electric buses.
While announcing his policies, Mr Goff also took a shot at rival Mr Tamihere, saying he is not fit to deal with the congestion and pollution challenges that Auckland currently faces.
"A Tamihere mayoralty will set Auckland back; my next term will take Auckland forward." Mr Goff said in a statement.
Mr Goff's first term focused on the investment to protect Auckland's environment.
This included reducing sewage overflows within a decade, a massive increase in funds to stop kauri die-back spreading, and pest eradication.
"We will achieve in less than a decade what the council thought would take 30 years when I became elected," he said.
