Avid mountain-biker and Rotorua businessman Ray Cook has donated the use of a new digger to the Rotorua Trails Trust, a move trustees say is a "game-changer" for forest users.
Mr Cook, of R & B Consultants, said his company would retain ownership of the digger but it would be made "exclusively available" to the trust.
Another Rotorua-based businessman, Paul Pedersen of Lumbercube, also assisted with the project by helping source the Cat 301.7D CR mini hydraulic excavator for Mr Cook.
"I think those trails - mountain biking, walking and horse trails - are a very important part of Rotorua and need to be kept at a high standard. I hope this is going to help this happen," Mr Cook said.
"I enjoy the trails myself as a keen mountain biker and wanted to put something back into the forest. I'm pretty passionate about the forest and I really hope it helps the trust maintain what is a great forest network for all users."
