Geekzone is #1 for me, many times over. I used to like Trade Me for NZ-based sellers, though I don't use it so much now. I only use Google when I specifically want to narrow a search to NZ sites, then the localised version is handy, otherwise Startpage or DuckDuckGo. Most NZ sites I visit only rarely, Stuff in a blue moon or TV1 or TV3 for something on-demand that I missed. Most of my other interests are outside NZ.
