The figure compares with a net NZ$10 million sold in October.
Back in June, the RBNZ sold a net NZ$736 million when it intervened on foreign exchange markets for the first time since the New Zealand dollar was floated 22 years ago to limit the rise in the kiwi. The figures are not a direct and complete indication of the amount spent on intervention and include liabilities of the New Zealand government's Debt Management Office.
Data from the central bank also showed its net short currency position - a figure which the RBNZ has said better reflects its currency dealings - rose to NZ$2.48 billion from NZ$2.4 billion in October.
Given that they began intervening at 0.7620 on 11 June 2007, their average is probably around 0.7700. So they are breaking even at present.
Lets hope they have learned, that it is best to let the markets find their own level.
What that true level is, nobody knows, least of all a central bank.
