Nicky Hager's new book comes as no surprise to local election candidates who are well aware of the "dirty tactics" used in politics.
Investigative journalist Nicky Hager had on Wednesday released his book, Dirty Politics, which features leaked emails between National Party figures and right-wing bloggers.
Mr Hager said anyone who read the book would find chapter after chapter of remarkable things Prime Minister John Key had done and had to answer for.
Tauranga National MP Simon Bridges said based on what had been reported in the media about the book it contained several conspiracy theories and unfounded allegations.
"I agree with the Prime Minister. Voters would see it for what it is," he said.
