Hansen, familiar with how Welsh rugby is run after more than four years as national coach or assistant coach, wasn't surprised to learn six weeks ago that the WRU was seeking to repeat the protocol of last year, when the Welsh anthem was the final act before kickoff to mark the Wales-New Zealand centenary.
NZPA understands All Blacks management was frustrated the WRU never gave a coherent reason for wanting to change the traditional protocol again, with the explanations constantly changing over six weeks of negotiation.
Management was also angry the WRU had gone back on an agreement last year that the change would be a one-off.
