This river has a small, steep catchment and is therefore quite flashy. While the Wairua is still flooding over its banks this little gem will have been up and returned to its normal flow. From the put-in the river is tends to be rather boney; if it isn't then the gorge section will be very interesting. For the first 1.5 km the river contains boulder and gravel rapids with some 1 to 2 metre drops at the ends. Just as you're thinking to yourself, there is not enough water in this river, the banks close in, constricting the flow into a smaller bedrock channel for the next 2 km. This section contains the hardest rapids, becoming pool drop with a few longer class III rapids. It is quite confined in places but can be mostly boat scouted although a quick check down some of the longer shoots might improve safety and ease your nerves. When the Waiokumurau stream comes in from the right you are through the hardest section. The gradient eases and the river widens again returning to the boulder and gravel rapids but this time with greater volume. These rapids keep up the fun for the next 5.5 km down to the take out. When you leave your shuttle vehicle at the take-out take time to familiarise yourself with the surroundings as it might be easy to miss from the river. To get to the put in: From Whangarei take SH14 to Mangatapere, here turn right towards Tetoki, follow this road through the village until you get to Twin Bridges. Here turn left just before the bridge and follow the road up the valley for a further 11 or 12 km. Leave a shuttle vehicle where the river leaves the road for the last time . Continue along this road until you get to a T junction at Waimatenui, turn right and follow it down hill to the bridge. Park at the bridge and get in on the down stream side on the left hand side of the left channel after a brief excursion through the bush.
