Great little video Martin. Takes me back as my company was one of the pioneers of rafter the lower Mohaka - 1983 to 1996. Grade 3 down to the Te Hoe junction (which is what you have shown here) and grade 5 Mohaka gorge down to Willow Flat. We mainly used 4.2 metre Lancers but did it in 4 man rafts a few times and that was great fun, albeit with quite a few spills in that Te Hoe drop section as shown in your video. The gear has progressed significantly since then!
