"The strategy hasn't changed for BBL, which is really about capitalizing on the opportunity to draw news fans in our own backyard and I still think there's plenty of upside in that.
"New Zealand is a market that we know has huge interest and there's no question having North and South Island teams would work well from a New Zealand perspective, but it really has to fit in with the broader Cricket Australia strategy."
While Heat slugger Chris Lynn claimed he would rather play Big Bash than international limited overs for Australia, Everard insists the BBL is not designed as an alternative to national honours.
"That's a minority view," he said. "There's no question the opportunity to represent your country on the international stage is still very much at the forefront of players minds.
"But the responsibility is really incumbent on administrators, on myself and others at Cricket Australia, to come up with a scheduling scenario that's the best of both worlds.
"There are certainly worse problems for sports to have. Essentially, Cricket Australia has two premium products in the market - international cricket and the growing Big Bash League.
"That's nearly 80 days of content to schedule, whereas six years ago, we had half of that. So, good problem to have, but certainly a challenging one to fit everything in."
The 2016/17 edition of the competition reaches its climax tonight, with the final between Perth Scorchers and Sydney Sixers.
NZ White Ferns captain Suzie Bates will lead the Scorchers into the women's final against a Sixers outfit that features international team-mate Sara McGlashan.
