Tony Lamborn was born in New Zealand but qualifies to play for the Eagles through his American father. At just 16-years-old, Lamborn left Ashburton College to pursue a career in rugby. He was rewarded with selections to the Hawke's Bay U18 and U20 teams.
In 2013, he made his debut for the Magpies of the Hawke's Bay Rugby Union. It was in 2015 when Lamborn started to make waves, however. He was named the Hawke's Bay 2015 MVP and helped the team win the ITM Cup championship, earning the squad a promotion to the Premiership.
In 2016, Lamborn was named as a member of the Hurricanes (Super Rugby) and has made four appearances with the team. Lamborn's Men's Eagles debut came in San Jose against Italy in June 2016. He recorded a try in his first appearance.
