The Barbarians have called up last weekend's Bledisloe Cup match winner Colin Slade to take on Australia at Twickenham on November 1.
The New Zealand first-five converted a last-minute try in Brisbane to rescue a 29-28 win against the Wallabies.
Despite those heroics he was judged surplus to requirements by New Zealand for their Northern Hemisphere tour following the recalls of Dan Carter and Aaron Cruden.
But Slade will head north to take on Australia in the Killik Cup match after Barbarians Head Coach John Kirwan completed his squad selection for the programme which includes a match against Leicester Tigers at Welford Road on November 4.
In the latest additions, the Crusaders fly half is joined by New Zealand back row forwards Steven Luatua (Blues) and Matt Todd (Crusaders) as well as by lock Dominic Bird (Crusaders).
