The Blues are being lined up to play France in a midweek game during the Super 15 recess in June.
NZRU chief executive Steve Tew confirmed a range of issues about the gate proceeds and player payments still had to be resolved but France were keen to take up the NZRU offer.
The match is likely to be played at North Harbour Stadium on June 11 following the tourists opening test against the All Blacks at Eden Park four days earlier.
"We wanted to offer them a game and it was up to them if they had any interest," Tew said.
"The change of heart was theirs not ours."
