Australia and New Zealand had health concerns on Thursday as the two sides prepared for the final match in the Chappell-Hadlee Trophy one-day series.
Australian batsman Michael Clarke, who scored 82 not out to help his side to a two-run victory in the second match, has gastroenteritis.
"We'll just have to wait and see how he pulls up," Australian team physiotherapist Errol Alcott said.
Fast bowler Brett Lee has already returned home to see a specialist about a nasal condition that has caused him breathing problems. He has been replaced in the Australia squad by the uncapped Mitchell Johnson.
New Zealand fast bowler Shane Bond, who missed the games in Auckland and Wellington with a hamstring strain, has been ruled out of Saturday's final match in Christchurch.
Captain Stephen Fleming, however, may return to the side after having surgery to remove a tumour from his face.
Fleming, who also missed the first two games, played for his domestic side in a four-day match and could retake the captaincy from spinner Daniel Vettori, though coach John Bracewell said a decision would not be made until at least Friday.
Batsman Lou Vincent is likely to play despite being struck on the right leg by a Lee delivery and forced to bat with a runner in Wednesday's defeat.
Australia won the first match by 147 runs.
