The Nga Tapuwae o Toi (or Footsteps of Toi) track continues on from Burma Rd to Whakatane at the lower end of Mokorua Gorge. See this post for the part from Ohope to Burma Rd. Refer also to that post for pointers to DoC web site information about the track.
The Whakatane end of the track is not actually marked as the Toi track, but there is a sign on White Horse Drive calling it the Mokorua Walk. There are apparently no markers at the lower gorge end with the track name, or any other information about the track.
There is room for cars to park at the start on Burma Rd, and a car park at the Whakatane end, but no toilet facilities anywhere on or close to the track. Dogs and bicycles are not permitted on this track.
