The New Zealand international centre back, voted the London side's player of the year last season, suffered an ankle sprain in training on November 5 and missed both legs of his country's World Cup playoff defeat by Mexico.
"He will soon begin intensive rehabilitation, but no timescale has yet been set for a return to first-team action," West Ham said in a statement on their website (www.whufc.com).
West Ham currently have a number of players out injured including record signing Andy Carroll, who has not played a game for the club since joining permanently from Liverpool in the close season.
