He has also played for the All Blacks since 2016, while O’Sullivan is the daughter of jockey Lance O’Sullivan.
The couple first confirmed their relationship through a 2024 Instagram post O’Sullivan captioned “a decade later”.
Several All Blacks WAGs left supportive comments on the carousel, including Hannah Barrett, who is married to Beauden Barrett, and Mackenzie Webb, Will Jordan’s fiancee.
It is unclear how the couple met but McKenzie is known to have studied at the University of Waikato, near where O’Sullivan grew up.
O’Sullivan was previously engaged to Israel Whitley, as announced by the Herald in May 2022.
Whitley is now in a relationship with influencer Tobi Innes, the daughter of former All Black Craig Innes and modelling agent Sara Tetro.
