Hockey New Zealand are welcoming the possibility of expanding the trans-Tasman trophy series.
The current series involves both the men's and women's sides with the possibility of adding age grade sides from under 18 to masters being weighed up for the future.
Hockey New Zealand High Performance Director Terry Evans says they have a strong relationship with Australia so it'd make sense to expand the tournament.
Evans says it'd be a great opportunity to compete against Australia in a unique format across all ages which would make for a significant tournament.
The Men's Black Sticks are currently in Melbourne for the upcoming Festival of Hockey which will feature one off tests against Australia, Malaysia and India.
