The Rollerpark is open to skateboards, BMXs and rollerblades (and even once a uni-cycle!). This park is a good size at 55m x 45m with lots of great features including a clover leaf bowl. It is widely regarded as one of New Zealand's best parks.
There is normally plenty of room for visitors and some days you may have the whole place to yourself. The park is located on The Strand behind Broadway.
