When journalist Ian Wishart unfolded a letter from the Ministry for the Environment he started to laugh.
"New Zealand needs people like you who contribute every day to protecting and enhancing our environment," read the letter telling him he had been nominated for a "Green Ribbon Award".
An author of two books rejecting man-made climate change, Mr Wishart was the last person to expect to be praised by the ministry.
Its awards praise "outstanding contributions" to "protecting and enhancing New Zealand's environment". Mr Wishart's books aim to debunk climate change with theories out of step with the ministry.
Mr Wishart has dismissed the praise as a form letter.
