Labour Minister Simon Bridges says he was aware of a smear campaign on the Whale Oil blog on union cleaning contracts for Government buildings - but it had no influence on his decision to change them.
Nicky Hager's book Dirty Politics raised questions about the Government axing of its agreement to hire cleaning companies for state buildings only if they were members of the Building Service Contractors of New Zealand (BSC) industry body.
It suggested a link between Dunedin-based company Crest Commercial Cleaning and Whale Oil posts critical of the BSC in 2012 and 2013.
In May, Mr Bridges announced that the Government was dropping the BSC agreement. But yesterday, he said that the decision had nothing to do with Whale Oil or Crest.
"We know that [blogger] Cam Slater or Whale Oil had a series of posts critical of me. If anything, those posts made me less likely to make the changes we made, not more likely.
