Looking for Winiata Whanau Nz

Kia Ora

I am searching for any information about my fathers maternal grandmother - his mums mother Rawinia Kaeke Winiata.
We know that she married Hirini or Kihirini Whatuira from Wairoa and that she is of Tuhoe.
Their children were Anihira (our grandmother), brother Roger and sisters Nanny Tao and Nanny Molly. There were others but at present not too sure of them all.
We would appreciate any information about this nanny.
