England's injury problems continued to mount after wing Christian Wade was ruled out for up to six months with damaged foot ligaments.
Wade will undergo surgery after being hurt in Wasps' 19-12 Aviva Premiership victory over London Irish on Saturday and will miss the entire RBS 6 Nations.
"It's devastating news for both the player and the club," Wasps director of rugby Dai Young said.
England announce three-Test New Zealand tour
England will play Tests in Auckland, Dunedin and Hamilton when they tour New Zealand next summer.
The series opens at Eden Park on 7 June, continues at Forsyth Barr Stadium seven days later and concludes at Waikato Stadium on 21 June.
One midweek match has been scheduled against seven-times Super Rugby champions the Crusaders in Christchurch on 17 June.
Three of England's 2011 World Cup group matches were staged in Dunedin, where they defeated Argentina, Georgia and Romania, while Eden Park was the setting for their 19-12 quarter-final loss to France.
The first Test takes place just seven days after the Aviva Premiership final at Twickenham and the proximity of the dates means England head coach Stuart Lancaster is resigned to being unable to field his first-choice starting XV until Dunedin.
France, Wales and Ireland will face the same complication following the Top 14 and RaboDirect PRO12 finals on 31 May for their 2014 tours of Australia, South Africa and Argentina respectively.
IRB chief executive Brett Gosper last week stated that steps are being taken to clear up any future confusion over when the international window opens.
