Do they (NZ) have an extradition treaty with us? Or are they close to an area that does NOT?

EXTRADITION
Extradition is an official process allowing for the surrender of a suspected or convicted criminal from one state to another. A country requesting extradition may rely on either an international treaty or on the domestic law of the foreign country. New Zealand’s extradition procedures are laid out in the Extradition Act 1999 (the Act) which governs the extradition of persons to and from New Zealand. The Act does not require a foreign country to have a treaty to request extradition from New Zealand.
The Ministry of Foreign Affairs and Trade is New Zealand’s contact point for all extradition inquiries. General information for countries seeking to make a request to New Zealand or New Zealand agencies seeking to make a request to another country for extradition may be found on the Ministry’s website.
