North Queensland's James Tamou and Kalifa Faifai Loa have been added to the national train-on squad to prepare for the Kiwis' end of season international programme in October and November.
The addition of prop Tamou and winger Faifai Loa follows the naming of nine players by national selectors Howie Tamati (convener), Stephen Kearney, Tony Iro and Tawera Nikau last week.
Tamou played for the New Zealand Maori in their draw against England last year while Faifai Loa was named in the NYC Team of the Year when he was with the St George Illawarra Dragons last season.
The latest selections follow the elimination of the Cowboys and Newcastle from the NRL finals race.
None of the Knights' New Zealand-eligible players were included.
