"We think we've got the right balance, all 18 girls deserve their spots and I know they are very excited."
The World Cup team is also bolstered by the inclusion of striker Katie Glynn and midfielder/defender Stacey Michelsen, who both missed much of the past 12 months with serious knee injuries.
Michelsen played well throughout the recent Hawke's Bay Festival of Hockey, while Glynn has been training hard in recovery from a torn ACL which she suffered in last year's Ford National Hockey League.
Whitelock said it was a huge bonus to have Glynn and Michelsen back at full strength, as well as Forgesson who has also been injured.
"It's awesome to have those girls back. Katie leads the girls up front, talks well to the others and gets them connected and of course can get the ball in the back of the net," she said.
"Stacey is very skilful and can break the line so sets up a lot of attack for us down that side and adds a lot to our game.
"We're shaping up well and are all looking forward to getting over to the World Cup. I played club hockey in The Hague so I'm pretty excited to play in front of their crowds, it's going to be huge."
The Black Sticks Women leave New Zealand on 18 May en route to Netherlands, where they will base themselves for a week of training before moving into The Hague four days before the tournament begins.
Their opening game is against Belgium on Saturday 31st May at 11pm (NZ time).
