Rotorua has announced it will hold a mud festival in December.
It's based on a similar event in South Korea which attracts more than three million visitors a year, and Boryeong City where it's based is a partner in the New Zealand event. Rotorua mud is very high in minerals due to the volcanic activity in the area.
It also stores heat easily when it's warmed.
Jason Cameron is major events co-ordinator for Rotorua Lakes Council.
