Hi, I'm aware theres some other quality issues around this import that need to be discussed first before resuming however I can maybe help out with licensing. I live quite close to a Statistics NZ office and are happy to go there next week and try get the waver signed for CC 4.0. Data has been imported into OSM from them before but that was under CC 2.0 - 3.0. CC 4.0 has different attribution requirements that unfortunately require a waver for OSM saying they accept the way OSM attributes them. For now as ❤️‍🔥 said, please hold off importing further data until more discussion takes place.

Thanks, Phoebe
