Both Delany and T-Pole have had previous spells at the Highlanders and have been brought in following season-ending injuries to Colin Slade and John Hardie.

Former All Black Delany, 29, played for the Highlanders in 2008, before going on to play for the Chiefs and then in Japan for Panasonic Wild Knights.

T-Pole also arrives from Japan, where he was part of the Ricoh Black Rams squad, with Tonga flanker having previously made 19 appearances for the Highlanders between 2004 and 2007.

The 32-year-old, who also played for Southland and the Ospreys, has agreed an initial three-week deal.
