Both Scotland and Wales are looking at contingency plans after their test matches against the All Blacks in New Zealand were called off due to the coronavirus.
On Friday, World Rugby announced all June and July test matches would be postponed due to international travel restrictions caused by the global pandemic.
Scotland haven't played the All Blacks in New Zealand since 2000, when current coach Gregor Townsend was part of the team, while Wales were last on Kiwi shores in 2016.
The Scots were due to play a two-match series against world champions South Africa before heading to Dundein to face the All Blacks on July 18, while Wales had two tests scheduled for New Zealand, along with a test against Japan.
Townsend understands why the games have been postponed, but is hopeful they get rescheduled for later in the year.
"To take on South Africa in a two-match test series doesn't come around very often," Townsend said.
"The fact they are world champions made it even more special. To go on from those two games to play New Zealand - who we've not played away from home since 2000 - would have made it the best, toughest, most challenging tour I can ever remember.
"I know our players would be better for the experience. Maybe later in the year we'll still be able to play some if not all those games, but we'll see.
"It's disappointing but it's insignificant when you see what the virus has done around the world."
Meanwhile, Wales' Kiwi coach Wayne Pivac was looking forward to the opportunity to face the All Blacks.
"We were very much looking forward to playing both in Japan and New Zealand in the summer," Pivac added.
"Having seen first-hand the welcome the team received at the World Cup in Japan, and the extraordinary scenes at the open training session, I am sure our fantastic relationship with Japanese rugby will go from strength to strength in the future.
"On a personal note I was really looking forward to returning to New Zealand with Wales.
"It's unfortunate we will now have to wait a little longer for that privilege, but the occasion will be no less relished when it arrives."
NZ Rugby chief executive Mark Robinson said his team is working hard " to explore any and every opportunity to play All Blacks tests as well as Black Ferns tests this year".
The All Blacks are still scheduled for a tour of Europe later in the year with tests locked in against England, Wales and Scotland.
