The row over police exerting controls over research has led to tertiary education minister Steven Joyce endorsing academic freedom and encouraging government agencies to be "as open with their data as is reasonably possible".
And government support minister Peter Dunne has also leapt into the fray, labelling the police position "absurd" and needing review.
The contract at the centre of the furore insists researchers accept police control over their work in return for access to information. While the contract talks about privileged information, it was applied to a basic data request for researchers studying crime patterns around licensed liquor outlets.
Researchers are told to allow police to help "improve" research which shows "negative results", with the threat of a possible "veto" on publication and a "blacklist" if they break the deal.
It was exposed by Canterbury university criminologist and gang expert Dr Jarrod Gilbert, who was told he was personally banned from the data because he had an "association with of gangs".
