Work has begun on the upgrade on the Hemo Gorge section of Rotorua's Te Ara Ahi cycle trail.
The section from Te Puia to the Rotorua Mountain Bike carpark in Waipa State Mill Rd will be closed 7am to 4pm weekdays, except for Christmas Eve to 2 January.
Riders will need to use the on-road cycle lane into Waipa State Mill Rd until works are completed in late January.
Rotorua Lakes Council Sports & Recreation manager, Rob Pitkethley, said opening up the Hemo Gorge as part of the initial build of Te Ara Ahi was a great addition to the national cycleway.
"It's a beautiful part of the trail that is used by hundreds of people on a daily basis. However it needs some refinement to ensure it meets the expectations for grade criteria of the cycleway, particularly for international tourists.
