Meanwhile, New Zealand Rugby is fuming after the announcement of the Rugby Championship schedule that has the All Blacks playing their last match in Australia on Saturday, December 12, which is a change from original planning.
The last scheduled clash against the Wallabies means players and staff will be stuck in 14-day managed isolation over Christmas, a situation NZR were hoping to avoid.
Sanzaar and hosts Rugby Australia announced the match schedule for the Championship, with the All Blacks scheduled to play Australia in Brisbane on Saturday, November 7 and Argentina the following Saturday in Sydney on November 14.
The team is then scheduled to play back-to-back tests against South Africa in Sydney on November 21 and Newcastle on Saturday, November 28, with a second test against Argentina on Saturday, December 5 in Sydney and a final scheduled match against the Wallabies in Sydney on Saturday, December 12.
