Redmayne, with her husband Richard, owns and operates the award-winning business Coastal Lamb at their Tunnel Hill farm in Turakina.
The electorate’s current MP, National’s Ian McKelvie, will retire at the end of this term.
Redmayne said she was feeling fantastic.
“When I first stood I said I was doing it because I thought Rangitīkei needed a strong, authentic voice in Wellington.
“That’s exactly what I’m going to do.
“I’m really passionate about rural and provincial New Zealand and our communities.”
She would be heading to the capital on Monday for an induction, she said.
“First and foremost, I want to cement my place in the electorate.
“I want to get out and about as much as I can. I worked in an MP’s office for 20 years so I know what I want to do.
“I want to be a really hands-on, approachable MP and a strong advocate for the people of Rangitīkei, and for everyone.”
