Have just received this response from Television New Zealand in response to an OIA request I made:
Damien Christie, OIA, TVNZ
Dear Mr Farrar
OFFICIAL INFORMATION ACT REQUEST
I refer to your request under the Act dated 8 April 2010.
Following an exhaustive search, and enquiries to the usual suspects, it appears that only one pair of pink handcuffs was purchased by Television New Zealand during the period of 1 March to 7 April 2010.
As I am sure you are aware, the handcuffs were purchased as a novelty prize for Back Benches. They were purchased from an undisclosed location in Wellington, and cost $24.99. I cannot confirm whether this represents a fair market price, or whether we paid over the odds for them.
General Counsel/Company Secretary
