Take the Main Range Track off the Puketui Walk and veer left onto the Water Race Tunnels Track. This follows the old water race that took water from the Third Branch Stream across the Tairua River via three tunnels to drive the Broken Hills Battery.

The original race was 3300 m long. At the southern end, the track joins the Water Race Link Track, where you can either drop down a stepped track for 15 min to the Puketui Walk and return to where you started, or climb up to the Third Branch Track and onto Collins Drive. 

Broken Hills is 19 km from Tairua and 27 km from Whangamata.

The two entrance roads (Puketui Valley Road and Puketui Road) to Broken Hills do not connect and a stream crossing is required between them.

Plan your journey so you access your destined track or campsite by the correct entrance road.

Puketui Valley Road entrance

Turn off SH25 at Hikuai onto Morrison’s Road (50 m north of the Pauanui turn off) then onto Puketui Valley Road. It is 6 km to the car park at the end of Puketui Valley Road.

Note: Tairua River Bridge, one km short of the road end, has a 10-tonne weight limit.

Puketui Road entrance

Alternative access is available off the Kopu-Hikuai Road (SH25a), 26 km from Thames. Turn on to Puketui Road 400 m before the Tairua River and Fourth Branch Scenic Reserve. A 4 km gravel road brings you to the Puketui Road car park at the southern end of Broken Hills. You will need to wade the stream to access the track system as there is no bridge across the water.

• Mine tunnels and shafts are very dangerous and may be hidden by vegetation.
• Keep to marked official tracks.
• Do not enter tunnels unless they are clearly marked for public access. 
• Carry a torch with fresh batteries.
• Warm clothing is recommended.
