The City Fitness gym in Wairau park is a really good gym. I haven't been to any of their other gyms around the place but this one was excellent. They have a really good weight and cardio area plus the bathrooms and showers are excellent. (They seem really new and are kept very clean.) Big-ups also to the guy at reception who always gives a friendly hello, even if its 6:30am in the morning and I'm still half asleep.
