The 500-m long Collins Drive provides an opportunity to experience a real underground mine system. This tunnel was driven through the hill in a fruitless attempt to find a quartz reef with payable ore. Dangerous shafts have been boarded up.

You will need a torch for the 15-min boardwalk through the tunnel. Turn your torch off near the tunnel entrances to see the glow-worms.

The easiest approach to Collins Drive is via the Third Branch Track (Puketui Road) or Water Race Tunnels Track (Puketui Valley Road). A small landing 5 min short of Collins Drive marks the start of an aerial cableway that carried ore hoppers to the Golden Hills stamper battery.

From the west end of Collins Drive, a 10-min climb to the ridge will bring you to the Main Range track. Turn to the east (right) and you will return to the Puketui Valley road end car park, approximately 1 hr away. Check out the views from the lookout on the way. 

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.
