Former All Black Assistant coach Wayne Smith has turned down an opportunity to join Stuart Lancaster in coaching the England national team due to personal reasons.
Smith is currently assistant coach with the Chiefs in Super Rugby and would not have been available for England until September.
Wayne Smith said: "I was very impressed with Stuart (Lancaster) when I met him. He is an outstanding individual and will be a great plus for England Rugby and anyone who works in his team will be very fortunate. England have some fantastic young players and the opportunity to work with them ahead of the 2015 World Cup was very appealing.
"It was an incredibly difficult decision but ultimately I have decided to stay in New Zealand, mainly for personal reasons."
England will tour South Africa in June and London Irish attack coach Mike Catt has been given a two month contract to assist Lancaster on the tour.
Catt was appointed on a temporary basis but this may become permanent as London Irish have also revealed that Catt will leave the Aviva Premiership Rugby club at the end of the season.
Catt will leave London Irish after their final Aviva Premiership match with Gloucester Rugby at the Madejski Stadium on Saturday and start work with England on May 7 through to June 30.
England Head Coach Stuart Lancaster said: "Mike has played at the top level and is highly respected. He has done a great job whilst coaching at London Irish and we are looking forward to working with him on this South Africa tour. "
"He is experienced in playing in South Africa and this will be invaluable as we prepare for this challenging and exciting tour.
"While Mike, Graham Rowntree and myself will lead on the coaching for the tour we will also have Jon Callard and Simon Hardy as part of the coaching team. Jon and Simon know the players well from their roles with the Saxons. "
"They will assist in the preparation and support to the midweek teams and they will provide excellent specialist support in their individual areas with Jon supporting our kickers and Simon our hookers throughout the whole squad."
Mike Catt said: "I was very impressed with England during the Six Nations, not just the way they played but the culture that is developing, and hopefully I can complement what Stuart and Graham are doing.
"There are some talented young players coming through and the chance to work with them for the Barbarians game and the tour is really exciting.
"I’ll be sad to leave London Irish and I want to say a huge thanks to all the players and coaches I have worked with since 2004. Toby Booth in particular deserves massive credit for what and how he has taught me."
