The Blues could be run from overseas under a new licensing model proposed by the New Zealand Rugby Union.
The national body is advertising for expressions of interest in four of the five New Zealand Super rugby franchises, with NZRU chief executive Steve Tew saying the search will not be limited to this country.
"We're quite happy to go beyond the borders of New Zealand," Tew said. "We'll make it very clear, though, these teams will be New Zealand-owned and continue to play in our competition in New Zealand."
The union signalled its intention to partly privatise its franchises two months ago and with this formal step out of the way, it's hoped licence holders will be in place by the start of the 2013 season.
Tew admitted yesterday that "there's not a lot of economic sense in many of the investments in professional sport around the world".
