Kyle Butters then teamed with Sam to win the Open Men's doubles title after a hard fought match against the Rotorua pairing of Tamai and Jesse Galvin-Dawson.
Younger sister Paris then added a third trophy as she was a comfortable winner in the Mixed Doubles final, as she and her partner defeated Auckland's Peri Woods and Tracey O'Connor.
The Butters' cousin Paige Hourigan was unable to take part in the three day tournament as she was preparing for the ASB Women's Classic qualifiers on Saturday.
Maori Tennis Association chairman Richard Garratt said as well as the Butters family there was a strong contingent of Whanganui players, continuing a long and proud tradition in Maori tennis.
"From the inaugural Marumaru Cup established in 1907 for their own Hauauru tribes, the trophy [was] named after prominent Whanganui kaumatua Tarau Marumaru.
"Whanganui hosted the second NZ Maori Lawn Tennis Championships in Whanganui in 1927, [and] Tukere Te Anga from Whanganui was president of NZMLTA from 1926- 1936."
In addition, a NZ Maori Tennis team played the touring British Isles team in Whanganui that same year in 1927, which was organised by Pei Te Hurinui Jones.
