The Green Party has confirmed it will not support the Government's urgent bill to make secret filming by the police lawful.
Prime Minister John Key this week announced plans to introduce a Video Camera Surveillance (Temporary Measures) Bill, which would suspend the effect of a Supreme Court decision earlier this month into the Urewera case.
The bill would effectively mean police, under a search warrant, could still use hidden cameras on private property to gather evidence.
Greens' law and order spokesman Keith Locke today wrote to Attorney-General Chris Finlayson informing him that the party would not be supporting the bill.
Mr Locke said the Greens would only in exceptional circumstances support retrospective legislation, and this was not one.
