Whare

The whakapapa merely says Whare, so an assumption is made here that this Whare is "Wharetipeti", tupuna of Ngati Whare.
Note : this is not his only wife.

NOTE TO SELF :  (4 Feb 2018)
Add this to the whakapapa of Whare = Ngauru

Hounuku - Heruika

According to Jim Forbes, Te Aue Hounuku (sister of Herepo, Mauriri ma) was married to Heruika. Her first husband by which she had a son, Tame Heruika.   I have made a note of this whakapapa, should confirmation arise that this "Heruika" is the same Heruika that married Waikaukau; although I am inclined to believe that this is a "namesake".
