Rangiriri was a rural New Zealand parliamentary electorate in the Waikato Region from 1978 to 1984.
[1] As part of the 1976 census, a large number of people failed to fill out an electoral re-registration card, and census staff had not been given the authority to insist on the card being completed.
Together with a northward shift of New Zealand's population, this resulted in five new electorates having to be created in the upper part of the North Island.
[4] Population centres for those six years included Pukekohe, Meremere, Huntly, and Ngāruawāhia.
When Rangiriri was abolished for the 1984 election, Birch transferred back to the Franklin electorate.
