Act Leader Don Brash has used Nazi analogies to attack local body bosses.
In a speech today to the Federated Farmers annual conference, Brash said he is constantly hearing horror stories of the "little Hitlers" who he claimed populated the lower levels of local and regional government.
The comments came up as Brash was advocating for further reforms of the Resource Management Act.
Brash said bureaucrats throw their weight around and sometimes refuse to grant RMA consents on flimsy excuses.
He also attacked RMA rules that require consultation with Maori, saying communities should be consulted equally without racial preference.
The former National Party leader also suggested global warming might not be all that bad in the speech.
He reiterated Act's desire to scrap the Emissions Trading Scheme and challenged the science behind global warming.
He said even if a case can be made that human activity is behind an increase in global temperatures, it is not obvious that this is necessarily a bad thing.
Brash said human societies thrive in both Singapore and in Finland, even though average temperatures in both places are very different.
