An out and back day mission to a challenging river in Kahurangi National Park. Thanks to Aaron Reimer for permission to use his trip report as a basis for this trip page. Aaron thinks there are options to extend the trip upstream (with harder rapids than this section) and downstream (more mellow rapids) of this section described. There were a few discussions about the grading of this trip on the facebook group, so we look forward to further descents to confirm the information.
Wangapeka Track from Rolling Junction to Kings Creek Hut
Its about 3hrs 30mins from the Rolling Junction carpark to Kings Creek Hut. In 2012, a huge slip about 1h 30mins from the carpark caused a huge lake and gnarly rapid to form. The slip is still quite unstable (2017), with further rock fall possible, or even a dam burst and flash flood.
The Wangapeka Track page on the DOC website has more information about the track, huts to stay in and alerts about the dangers of the slip.
Wangapeka River (III/IV) from Kings Creek Hut to Slip Lake
Aaron reported some class IV drops, as well as sections of class III. He was able to portage the harder rapids.
Slip Lake and Slip rapids (P)
The size of the lake appears to have changed over time, but there’s still an obvious lake. The large slip is very visible on the true right side, which is where the access track and portage route goes. The Slip rapids look un-runnable.
Wangapeka River (III) from slip rapid to Rolling River junction
Aaron reported that the paddling gradually eased to class III by the Rolling River Junction
Aaron reported a flow of 50 cumecs on the Motueka at Woodstock gauge for his trip. The Wangapeka is a tributary of the Motueka, and showed the same flow behaviour on the storm cyle before his trip as the Wangapeka at Walter Peak. With that in mind, I’d suggest the Wangapeka and Walter Peak would probably end up being the main gauge for this trip in the future.
