The worst form of censorship is self-censorship.
Conservation Minister Nick Smith illustrated that by eliciting a sanitised version of a DoC draft report which in an earlier guise contained serious misgivings about the Ruataniwha Dam proposal.
The minister denied interference, yet paradoxically said he would have been "negligent" not to discuss statutory aspects of the Hawke's Bay Regional Council proposal with senior DoC staff.
He maintained it wasn't a straight-forward matter as he was the man who would eventually make a ruling on the Board of Inquiry's recommendation on the proposal. Due diligence is an all too handy crutch.
Obliquely, or directly, he sparked the paraphrasing of a 32-page submission into two paragraphs.
