In these current (left) and past maps, the changing course of the river over time has been mapped by fluvial geomorphologist Jane Richardson of Massey University. The palaeovalley refers to the changing drainage patterns of rivers.

The sound of boulders moving down the river, one form of the changing river landscape, was mentioned in an interview with a farmer whose farm was adjacent to the Waiwhakaiho.
