Born in Miramar, Wellington, Marino Mikaele Tu'u moved to Hastings when he was 11 years old. Tu'u began playing competitive rugby when he made the Hastings Boys' High School First XV in 2013 as a Year 11 student. In 2014, Marino was selected for the New Zealand Barbarians and in the following year, was selected for the New Zealand Schools side at No.8. In 2016, Marino made his Hawke's Bay debut in the Mitre 10 Cup against Canterbury and was also again selected for the 2017 squad.
Marino had a few opportunities in 2019 and will be looking to take advantage of those presented in the 2020 season to cement his position within the loose forward stocks.
