Not quite. See s131(5)(a) of the same Act. Criminal copyright infringement in NZ can carry penalties of up to five years' imprisonment, which is well above the 12-month limit needed to trigger the Extradition Act 1999. The key element in s131 is that the infringement is 'in the course of business' (i.e. for material gain) or 'otherwise than for [personal use]'. I think Megaupload.com would probably satisfy these conditions.
