From the cairn on the Oruinga highpoint, head 80m east then swing NE down a defined spur, dropping through tall tussock and letherleaf to the saddle with Broken Ridge. The start of the spur is hard to find in poor visibility, and a compass is useful.

Once over the saddle, vegetation changes to short tussock for the climb to the south-easternmost knob on Broken Ridge. This is the unmarked junction with the track up from Hinerua Hut to the east.

Note: Described in the reverse direction to your journey

From the knob where Broken Ridge forks, drop south (on a 190 degree bearing in bad weather) down a spur that heads for the saddle with Ohuinga. Swing west off the sour onto the saddle (this turn again is hard to spot in bad weather), dropping into tall tussock and leatherleaf. Beyond the saddle, a 200m climb follows up the defined spur, still in thick tussock and low leatherleaf, to reach Ohuinga highpoint.

A cairn marks the summit, and the junction with the routes to Tarn Biv / Black Ridge to the SE, and Iron Peg / Purity Hut (etc) to the NW.
