Wai-O-Tapu Thermal Wonderland has a unique landscape featuring one of the most extensive geothermal systems in New Zealand. However, this harsh environment takes its toll on timber sign posts, fences and boardwalks.

The park is currently trialing a Replas 100 mm bollard in an area that is off limits to the public due to its higher than normal ground temperature. Alex Leinhardt from the park says, ‘In some situations within this harsh environment, the life expectancy of conventional timber is less than in other locations’. If deemed a success recycled plastic may be given consideration as an alternative to traditional timber. According to Alex the bollard, ‘has now been in the ground for about a month and is showing no outward signs of deterioration’.
