Although it has yet to be confirmed, it seems certain that Stead will skipper the side in the Shell series following the off-season retirements of Lee Germon and Darrin Murray.

Otago will remain in the province to play the New Zealand Academy from Monday to Wednesday at Lincoln Green. The Otago team includes former Wellingtonians Stephen Mather and Glenn Jonas, who have shifted south in the off-season.
