I've quite a range of interests, which should be apparent from where I've edited pages, but I also love the random article functionality.
The WikiProject New Zealand has become a focus of my attention, especially in working on the pages needing work and the missing pages, although articles from anywhere may catch my eye.
SuggestBot suggested a few things for me to work on, so as usual I was making a start on the list when I was distracted by the mass of red links on the New Zealand electorates page, with the result that I'm working to create at least stub articles for the current NZ electorates. I'm hoping others will fill in some of the missing information as there is so much to do (not exactly unusual for WP).
There is also the WikiProject New Zealand - Vandalism patrol page which tracks recent changes to high vandalism pages which I keep an eye on from time to time.
I also keep an eye on new pages and featured articles, watching for vandalism with the help of Popups and Twinkle.
