The Warriors have strengthened their outside-back depth after losing Roger Tuivasa-Sheck to injury and a move to Super League.
In the past two seasons, they signed Alofiana Khan-Pereira, Grant Anderson and Will Warbrick, and extended Rocco Berry through 2027.
Ali Leiataua has also developed, while Leka Halasima played centre in the Warriors' finals matches this season.
With injuries and Taine Tuaupiki's rise to fullback reshaping the backline, 31-year-old Charnze Nicoll-Klokstad has been used in the outside backs.
He made 16 appearances for the Warriors this past season and represented the Kiwis at the World Cup.
London Broncos and Catalans Dragons pursued him last year, before he signed a one-year extension to remain in the NRL for 2027.
Love Rugby League reports that several clubs are interested, with St Helens favourites to sign him.
St Helens finished seventh and missed the finals after a coaching upheaval.
Paul Rowley stepped down in July, Eamonn O'Carroll became interim coach, and Kevin Walters signed the following month after exploring options with previous NRL experience.
Tuaupiki recently extended his Warriors contract through 2029, two months after September rumours that he wanted to explore Super League options.
