History of these domain names (being both peak.nz and nui.nz) is that they were acquired for a personal project to create an online space (Forum, private social network, or other web CMS) for organizing outings and events informally and casually between a small group of friends away from relying on Centralized and Commercialized Networks such as Facebook and Meetup

Part of the prescription was that this new “space” had to be accessible via Mobile, the domain names needed to be easily typed in to a mobile device and in this case, shorter the better. Appears with the .nz domains names not being as recognisable or respected as the .co.nz ones, both of the aforementioned domain names were freely available for registration at the time (and had been for several months after the DNC Preferential Rights of Registration period had ended),

However, the project, apart from setting up multiple props for evaluation, in effect never took off and it was at this stage, the allure of facebook was found / assessed to be nigh impossible to break for the social circle that it was intended for (the same social circle, which originally suggested creating an alternative), and I have since decided to pick up and use these domains myself for my own personal use.
