New Zealand hooker Sione Tupou played in Major League Rugby during the 2026 season. He represented the New England Free Jacks for his entire MLR career.

Not to be confused with the former Tongan Sevens captain of the same name, Sione Tupou attended De La Salle College in Auckland while also joining the Bay of Plenty pathway. In 2024, he was selected to join the Chiefs U20 side and later that same year Tupou earned his NPC debut for the Steamers, earning a pair of appearances off the bench against Otago and the Tasman Mako. The following season, Tupou would increase this to 5 appearances for the Steamers during their NPC campaign, more than tripling his gametime minutes.

On 10th December 2025, the New England Free Jacks announced the signing of 21yo hooker/prop Sione Tupou for their 2026 title defence, joining fellow Steamer Jacob Norris and Bay of Plenty prospect Filipe Vakasiuola as well as Free Jacks Captain Joe Johnston, another Steamers player.
