Tuahu Kauri sits within Kaimai Mamaku Conservation Park in the Kaimai Ranges, offering visitors a chance to see a mature kauri tree via a short side track from the main Tuahu Track. The area lies at the end of Hot Springs Road, just south of Katikati off State Highway 2. The main Tuahu Track forms an east-west crossing of the ranges that has been used since the 1890s. A brief detour reaches the kauri, while the longer route continues across the range with river crossings and summit views. The park is managed by the Department of Conservation and features native forest, historic routes, and lookouts such as Sentinel Rock.

About Tuahu Kauri
The Tuahu Track begins at the car park at the end of Hot Springs Road and follows an historic route across the Kaimai Ranges. A short side track leads to the Tuahu Kauri, a mature stand of kauri trees that includes one of the largest remaining in the Bay of Plenty region. The main track continues with a stream crossing and climbs toward the summit, where it meets the North South Track.
Beyond the summit the route sidles along the western escarpment, providing views over the Waikato plains and Killarney Lakes before descending through pine forest toward Wairakau Road. The full crossing is rated an advanced tramping track and requires good preparation, including a topographic map.
The Sentinel Rock Lookout Track branches from the Tuahu Track near the kauri trees. It involves a steep climb along a ridge to a viewpoint overlooking the rock outcrop and surrounding valleys. The old route directly onto Sentinel Rock itself is considered unsafe and should not be used.
Kauri dieback hygiene is essential. Visitors must clean footwear before and after entering kauri areas and stay on formed tracks to help protect the trees from the soil-borne pathogen.
Tuahu Kauri Side Track
The short side track to the Tuahu Kauri leaves the main Tuahu Track after roughly 10 to 20 minutes of walking. It reaches a platform that allows close viewing of the large kauri without disturbing the root zone. The tree stands as a remnant of the once extensive kauri forests that covered the ranges. Return the same way to rejoin the main track.
Sentinel Rock Lookout
The Sentinel Rock Lookout Track starts at the Tuahu Kauri junction and follows a steep, undulating ridge to a viewpoint of the isolated rock outcrop and the wider valley. The track is approximately 5.4 km return and takes several hours. Spectacular views are possible on clear days, but the final scramble onto the rock is closed for safety reasons.
What Visitors Often Say
The short walk to the kauri platform is rewarding and suitable for most fitness levels, with native bush and a chance to see a large ancient tree up close.
The longer Tuahu Track crossing offers a genuine tramping experience with river crossings, varied terrain and expansive views from the ranges, though it requires preparation and is best for experienced walkers.
