Wellington:Medium pace bowler Kyle Mills on Tuesday withdrew from the New Zealand cricket team to tour South Africa in late October and November because of a calf injury.
His place in the 15-man squad for the two-Test tour has been taken by right-armer Iain O'Brien.
"The selectors are not satisfied that Kyle will be fit enough to leave with the Black Caps Test team next week and decided today to remove him from the test section of the tour," New Zealand manager Lindsay Crocker said.
"It is hoped that when Kyle recovers from his injury and has some game time under his belt he will be considered for the one-day section of the tour," he said.
Mills was due to return to international play on the South African tour after being sidelined since January with injuries. His withdrawal has provided an international recall for O'Brien who played two Tests for New Zealand in the 2004-2005 season.
