From Apiti Hut, drop down the track to the Opaewai Stream and follow it upriver. The river is of moderate size, but less than knee deep in normal flows and has good river-rock banks to walk on. Several crossings are required, but going is generally easy until 300m below the Opaewai-Purenga confluence. Here a brief rapid/gorge requires a scramble up boulders to pass it. Once past this the valley flattens again and the confluence of the Opaewai and Purenga is soon reached.
A track joins here from the ridgeline to the west (this track can be used to bypass this lower section of the river, but given that the hard part of the river is further upstream, it makes little sense to use this track. For a wet-weather route, head instead to Saddle Hut, and take the route along the ridge heading north to join the Twain-Waikokopu track east of Te Whakaumu).
