England defence coach John Mitchell has signed a contract extension with the Rugby Football Union until the end of the 2023 World Cup.
Mitchell, who has already worked with number of teams previously including England (1997 to 2000), Ireland, United States and New Zealand joined the red rose team in 2018 replacing Paul Gustard, who left the role to take up the director of rugby position with Harlequins.
During his tenure as head coach of New Zealand, the All Blacks finished third in the 2003 World Cup after losing the semi-final to Australia with a 22-10 margin.
The 56-year-old played in six uncapped matches for the All Blacks in 1993 during the tour of Britain. He also captained the side to win in three games against Scottish Development XV, England Emerging Players and a Combined XV side.
"I'm really happy to sign this contract extension. I'm thoroughly enjoying my time here with England and working with such a talented group of players, coaches and staff," Mitchell said in a statement released by the England board.
"It takes a long time to really build these relationships and I wanted to continue to carry on the work that we're all doing to achieve just what we're capable of here with England.
"I also think it's the right place for me to evolve and challenge myself as a coach, I'm learning all the time and that's only going to help me to improve the players and contribute more to this team.
"I really feel we have the potential to do some special things here."
England coach Eddie Jones, who himself signed a contract extension last year with the RFU until the showpiece event in 2023 believes Mitchell's experience will benefit the side in achieving their goal.
"I'm very pleased to have Mitch here with us as we work to our goal of winning the World Cup in 2023.
"He's an experienced and skilled test coach and adds great value to the coaching staff and player development."
