New Zealand's number one bowler Shane Bond has been declared fit for the third Test against West Indies beginning in Napier on Saturday.
Bond pulled out of the second Test in Wellington with a stomach virus just before play began and was replaced by Kyle Mills, who took 6-82.
New Zealand lead the three-Test series 2-0 and if Mills is retained, Chris Martin may be the player to make way.
An unlikely alternative would be to drop both to play two spinners.
Captain Stephen Fleming said Bond would not be rested to keep him fresh for the tour of South Africa.
"I think it's important he's at his best when he's bowling and if he stops bowling he can pick up potential injuries.
"I would like to keep him bowling if he's match fit."
Fleming expects conditions in Napier to be less helpful for his bowlers.
He said: "We are looking for improvement in every Test. The first Test we scraped through, the second Test we were pretty good.
"When Shane comes back we have another dynamic in attacking them. The Napier wicket is pretty flat so it's going to be hard work for the bowlers.
"From a batting point of view we will need some big partnerships."
New Zealand squad: Nathan Astle, Shane Bond, Stephen Fleming (captain), Peter Fulton, James Franklin, Jamie How, Brendon McCullum, Hamish Marshall, Chris Martin, Kyle Mills, Jeetan Patel, Scott Styris and Daniel Vettori.
