Auckland mayoral contender John Tamihere is facing growing criticism for promises ranging from freezing rates to privatisation of water.

The main challenger to mayor Phil Goff has announced a number of policies that politicians have described as "fantasy stuff", "irresponsible" and "desperate".

Not surprisingly, the former Labour MP and talkback host has hit back at his critics as he seeks to convince voters to give him a shot at running the Super City and managing a $7 billion annual budget.

In the past few weeks, Tamihere has announced controversial policies to turn the Auckland Harbour Bridge into a double-decker structure
