Chase Tiatia is a rugby union player, who currently plays as a utility back for Hawke's Bay in New Zealand's domestic National Provincial Championship competition and the Western Force in Super Rugby. He was born and raised in New Zealand, but is eligible to represent Manu Samoa internationally due to his Samoan heritage.

The National Provincial Championship, often simply called the NPC, is an annual round-robin rugby union competition in men's domestic New Zealand rugby. First played during the 2006 season, it is the second highest level of competition in New Zealand alongside the Ranfurly Shield. It is organised by New Zealand Rugby (NZR) and since 2021, it has been known as the Bunnings NPC after its headline sponsor. A concurrent women's tournament is also held, the Farah Palmer Cup.
