Looking for family and my iwi tribe

My mothers name Georgina Elizabeth Rauoriwa Anaru - born Carterton NZ 26-Sept / 1939 died May-30 2009 Hamilton NZ

Looking for family members of Anaru. She used to be called Jean for short and also went by the surname Andrews.
She's well travelled in NZ . Last know location was Chartwell Hamilton Waikato.

Have found out she liked singing and went under the name Kadean Del Riego
