Wainui Hut Track is a 7-mile (about 11.3 km) out-and-back from the Canaan Downs Campsite car park, following Moa Park Track to Wainui Saddle and Wainui Track down to the hut. Allow about 3 to 3½ hours. It suits a moderate day on foot: first you climb to an open saddle, then drop into forest beside the Wainui River before retracing the same ground. I’d choose it for an inland walk with a hut as the destination; there’s no summit finish. This is the direct hut return, not the longer Evans Ridge circuit or the through-route past the hut.
