From Wairoa, head towards Lake Waikaremoana on SH38. Cross the bridge heading into Frasertown and turn right onto Mangapoike Road. Follow Mangapoike Road for about 17km. Turn right onto Hereheretau Road and keep going for about 4.5km.
Watch out for a pond-like swimming hole and a rock-slide on the left-hand side. Park next to the road and follow the path down to Makaretu Stream.
