After playing Tane Samuels — nephew of fan favourite TK Samuels — on Shortland Street in 2007, Dominic Ona-Ariki took a break from screen acting. He'd previously had another lead role — as the time-travelling Fred on sci-fi series P.E.T. Detectives. From 2016 he became a regular on New Zealand screens — he acted on Filthy Rich, and played All Black Eric Rush on mini-series Jonah. He went on to take the lead role in local detective drama One Lane Bridge (due in 2020), as a detective with spiritual gifts. Ona-Ariki's big screen roles include 2017 comedy Gary of the Pacific, and 2019 gang drama Savage.
One Lane Bridge is a character-focused crime drama with a dark, supernatural edge. The series stars Dominic Ona-Ariki as Ariki Davis, an ambitious young Cook Island Māori Detective who, during a murder investigation at Queenstown’s infamous One Lane Bridge, inadvertently reawakens a spiritual gift that endangers the case, his career and his life.
