The RFU have yet to make contact with All Blacks Rugby World Cup winning Assistant coach Wayne Smith even though Andy Farrell has ruled himself out of a permanent position for England.
Saracens Head coach Andy Farrell has chosen to stay with Saracens which creates an opening or a specialist backs coach in Stuart Lancaster's England management.
RFU Boss Ian Ritchie has vowed to give Lancaster a "world class coaching team" to take England into the 2015 Rugby World Cup.
Smith is widely considered to be one of the best in the game but currently works for Super Rugby team the Chiefs as backs coach.
"I'm really happy here at the moment. I'm close to family and enjoying the game," Smith told the Telegraph.
"The NZRU have been great to me and I'm not desperate to coach overseas although one day I'd like to be in the Test arena again."
Unless circumstances change, Smith would not be available for England's summer tour of South Africa due to his commitments with the Chiefs.
That would mean the RFU having to appoint another interim backs coach for the three-Test tour, with Mike Catt from London Irish and former England coach Brian Ashton both potential candidates.
