Ms Whaitiri had four generations of the family present on election night at the Clive Rugby Club, including teenaged sons Wirangi and Nohorua Parata, but was preparing for an early start with a 6.45am Sunday flight to Auckland for TV interviews.
Aged 49, Ms Whaitiri had an election-night majority of 4279, more than three times that of her by-election win, with Mana Movement candidate Te Hamua Nikora having to settle for second place both times. He received the news at his election night gathering in Gisborne.
The votes totalled 18,820, well up on the low by-election vote and about 600 more than cast in the 2011 General Election in the electorate.
Ms Whaitiri polled 8614, Mr Nikora 4335, Wairarapa-based Maori Party candidate Marama Fox 3315, and Dannevirke-based Green Party representative Henare Kani was delighted with a poll of 1840. Independent candidate Cathryn Eden, of Napier, received 196 votes, and Australia-based The Expats representative Vicky Rose 76.
Ms Fox appears likely to win a place as a List MP.
Ikaroa Rawhiti was established in 1999, covering the area of six general electorates from East Coast to Hutt South, and the tribal regions of Ngati Porou - Potikirua ki Te Toka-a-Taiau, Te Aitangi-a-Mahaki, Rongowhakaata, Ngai Tamanuhiri and Hawke's Bay-Wairarapa iwi Ngati Kahungunu.
For most of the time, the region was in a Southern Maori electorate which included the South Island.
