Like Australia, there has been a lack of advertisement for the movie. Only since the movie has opened have there been any TV ads, which only screen in the morning.
The movie is running around four times a day in Wellington, but in one of the smaller theatre rooms. I took some friends of mine to a showing around 4:30 pm. Even though it was early in the afternoon on a weekday, there was quite a large crowd, roughly 30-odd people in a 50 seater room. The large majority of the crowd really liked the movie, even a few liked how the Kilrathi looked. People were also a bit disappointed with the lack of screen time they were given.
I was lucky to see the movie in the US when it first came out. When visually comparing it to the screening in New Zealand, the New Zealand showing was a lot lighter than the US, which is how it would look on the DVD I'm guessing.
