I also love the architecture in Wellington. Being a very hilly city means there are some very inovative designs to cope with the terrain. Most people who visit from Australia are taken by the wooden houses in Wellington. They certainly add a lot more character than your average 3 bedroom red brick house.
Wellington, like Canberra, has plenty of bushland within easy reach. From where I live, it takes me about 15 mins on my bike to get right away from all signs of the city. Of course one of the highlights of Wellington is the harbour. I love seeing the different moods and colours the harbour displays depending on the weather and time of day.
One big attraction to moving to Wellington is the climate. A lot of people think I'm mad because I didn't like baking in 40C heat for days on end in Canberra. Wellington's temperatures are very mild, and yes it can get a little windy in Wellington sometimes (not as much as people will lead you to believe) , but I find the winds very exciting. It's great to watch the clouds shoot overhead or the choppy waves on the harbour.
I take mostly landscape photos as that's where I spend most of my free time, but the other areas I like are architecture and macro photography. I particularly like macro work as it allows you to focus in (mentally and physically) on a very small area. It's amazing just how much more you can see when you stop to look at something very closely.
