Nick has produced a very good list of the main contenders. A few others that may be in contention:
Props: Josh Hohneck, Ben May
Hookers: Quentin MacDonald, Corey Flynn (plenty of options here!)
Locks: Romana Graham (if he isn't suspended by then),
Loosies: Liam Messam (unlikely to be available though), Trent Boswell-Wakefield, Zac Hohneck, Warren Smith, Nick Crosswell
Halfback: Piri Weepu (if not with the AB's), Chris Smylie
First-five: Dan Waenga (maybe?), Trent Renata, Willie Ripia (perhaps a long-shot, but he is back playing rugby in NZ)
Mid-field: Robbie Flynn, Tamiti Ellison (unlikely to be available), Tim Bateman
Outside backs: Andre Taylor, Kade Poki, Hosea Gear (as the AB's selectors will have dropped him by then..... nah just saying that to wind up Nick
)
There are probably a lot of others with Maori heritage that will certainly be in contention too.
From that lot I would go with a starting lineup, not including those likely to miss out due to injury (Dan Braid, Sean Maitland), or those likely to be with the AB's:
1. Ben May, 2. Hika Elliot, 3. Ben Afeaki, 4. Jarrad Hoeata, 5. Jason Eaton, 6. Nick Crosswell, 7. Tanerau Latimer, 8. Luke Braid, 9. Tawera Kerr-Barlow, 10. Trent Renata, 11. Zac Guildford, 12. Tim Bateman, 13. Charlie Ngatai, 14. Andre Taylor, 15. Robbie Robinson
Reserves: 16. Dane Coles, 17. Josh Hohneck, 18. Ross Filipo, 19. Karl Lowe/Dan Braid, 20. TJ Perenara, 21. Jackson Willison, 22. Kade Poki
