Work to complete the $500,000 toilet block at the Waipa mountain bike carpark should be finished by mid-March.
Rotorua-based Burton Construction foreman Robert Burton said work was progressing well and should be finished about two weeks ahead of schedule.
The new toilet complex would cost about $495,000 and includes four showers and changing rooms, as well as 12 new toilets.
The complex will be completely covered with dirt and will feature an overhead cycle bridge, providing a gateway into the Whakarewarewa Forest, and a central cycleway through the middle of the complex.
The much-needed facilities will provide high-quality facilities for the National Mountain Biking Centre of Excellence, which will be based in Rotorua.
