Black Caps pace bowler Trent Boult has been ruled out of the second test against Pakistan starting tomorrow, due to a knee injury.
Boult has some irritation in the joint of his right knee, which has been managed in recent weeks.
Doug Bracewell has been brought into the squad.
Black Caps Coach Mike Hesson said: "Trent has had a minor discomfort in his knee dating back to the tour of India, which we've been managing in recent weeks.
"Unfortunately he irritated it further while fielding in the first test. He bowled again and we were optimistic he would be ready for Hamilton, but during training on Wednesday felt further pain and has subsequently been ruled out of the Test.
