Hager pointed out the Dutch, England, Argentina and Australia have professional setups for the best players. There were lessons to be absorbed.
"We do well for what we've got, but I feel we can do even better."
A busy six months is coming up for Hager's women, who will move up a spot to world No4 on the strength of making the World League final, leapfrogging Australia, who failed to qualify for that event. They have a trip to Argentina, followed by the Commonwealth Games on the Gold Coast and the annual Hawkes Bay international festival before the World Cup in London in July-August.
And they are hoping for an invitation to the last six-team Champions Trophy in China towards the end of the year.
If New Zealand were feeling a bit lonely without their near neighbours at the World League, they'll see them at the World Cup.
The two teams have been grouped together in pool D, along with 12th-ranked Japan and No 13 Belgium for the 16-team major tournament on the international calender, alongside the Olympics.
World Cup pools:
Pool A: Netherlands (world No 1), China (8), Korea (9), Italy (17).
Pool B: England (2), United States (7), India (10), Ireland (16).
Pool C: Argentina (3), Germany (6), Spain (11), South Africa (14).
Pool D: Australia (4), New Zealand (5), Japan (12), Belgium (13).
