[2] He attended King's College, but at age sixteen was asked to leave after participating in a violent attack on a younger student.

While at university, he and his flatmates competed in an online competition for Dunedin's filthiest flat, and city health inspectors visited three times.

As of early 2022 he was the head of financial economic crime for Rabobank New Zealand, and was a partner in his wife's fertiliser supply business.

[9] He put his name forward for the National candidacy in the 2022 Tauranga by-election following the resignation of Simon Bridges in March 2022, and was officially announced as their candidate on 1 May.

[12] Uffindell's opponents in the by-election included sitting Labour List MP and cabinet minister Jan Tinetti and ACT New Zealand candidate Cameron Luxton.

[15][16] After the by-election, Uffindell announced that improving Tauranga's roads and tackling gang crime in the city would be his top priorities in parliament.

Uffindell denied these bullying allegations but did say he "enjoyed a student lifestyle", including drinking alcohol and smoking cannabis.

[24] On 11 August, it was reported that Uffindell's Dunedin flat, when he was at Otago University, was one of the filthiest in the city and that women's underwear had hung on a wall, apparently as trophies.

National Party deputy leader Nicola Willis said the photo of the "trophy" rack made her feel "pretty yuck.

The National Party announced the results the day of the Queen's funeral, saying that Dew's report found that while the attack at King's College was substantiated, the other allegations against Uffindell about his behaviour as a university student towards a female flatmate in Dunedin were not as reported; there were differing accounts and the allegations could not be substantiated.

[27] Only Wood, Luxon and Uffindell saw the report; deputy party leader Nicola Willis was excluded from the conversations and decisions about what conclusion would ultimately be presented to caucus.

[30] The National Party media team "blocked interview requests" for him during the campaign,[31] after he proudly stated that he did his family’s grocery shopping once a month "to give his wife a break".
