McKee was born in Lower Hutt. She moved to Rotorua in her teens, then returned to Wellington as an adult. McKee became pregnant when she was 24. Her partner died in a car crash a week before their daughter was born.[1]
Mckee was a strong critic of the Sixth Labour Government's gun laws, passed following the Christchurch mosque shootings of 15 March 2019.[4] The new restrictions on gun ownership and game animal management are the issues which propelled her to enter politics.[5] She met David Seymour, ACT's leader, through their opposition to those gun laws, and joined the ACT Party in June 2020.[1]
McKee ran for the electorate of Rongotai at the 2020 general election and was also ranked third on the ACT Party list. While she did not win the electorate, McKee was elected through the party list since ACT won 7.6% of the vote, entitling it to ten seats in Parliament.[6][7][8] In her first term, she was ACT's spokesperson for firearms law reform, conservation, justice and veterans.[9]
McKee contested Rongotai unsuccessfully for a second time at the 2023 general election, coming fourth place.[10] She was re-elected to Parliament for a second term as a list MP.[11]
In April 2024, Associate Justice Minister McKee and Prime MinisterChristopher Luxon confirmed that the Government would proceed with plans to reintroduce three strikes legislation, which had been repealed by the previous Labour Government. The new three strikes framework would only apply to sentences lasting at least two years, give judges greater discretion in cases where harsh outcomes would be "manifestly unjust," encourage offenders on their final strike to plead guilty, add strangulation and suffocation to crimes qualifying for three strikes sentences and demand a lengthy non-parole period for repeat murderers.[13]
On 14 June 2024, McKee confirmed that the Government would introduce new firearms legislation by 2026 to replace the Arms Act 1983. Proposed changes include reviewing the firearms registry and transferring the Firearms Safety Authority from the Police to another government department.[14]
McKee lives in Hataitai, Wellington. She is married, and she and her husband Duncan have four children.[1] She enjoys hunting and wool spinning.[5] McKee is Māori and her iwiisNgāpuhi.[16][17]
