Probably the best person to speak to in NZ is Stephen Macaskill. Stephen is currently in the process of setting up an exchange in New Zealand, see eg: http://www.interest.co.nz/business/87670/founder-worlds-second-largest-digital-currency-urges-regulators-get-banks-stop. Alternatively there are the people behind the Cryptopia https://cointelegraph.com/press-releases/cryptopia-launches-new-zealand-dollar-tethered-cryptocurrency who launched the NZ dollar tethered cryptocurrency last month who might be interested.
(While I am very interested in cryptocurrency and the blockchain, it is more from an academic lens - not the day to day business side. I'm a legal academic and I'm currently doing a project on the legal regulation of cryptocurrency in New Zealand and Australia - funded by the NZ Law Foundation - that's when I'm not doing presentations etc on blockchain. In NZ in particular there is a real lack of knowledge about cryptocurrencies and the blockchain, even amongst people you would think would have some knowledge including the majority of people in government departments.)
