New Zealand is ranked second in the competition below Australia, following their rise in rankings to fourth following the FIH World Cup.
"There is an expectation based on our ranking that we will medal and we believe it is healthy to have that pressure - I think it will help us perform," said Hager.
The team also became the first to model the new Glasgow 2014 official team uniform.
The uniform is traditional black and incorporates elements representing New Zealand's special character and place in the world, including a stylized Southern Cross, tui and the letters NZ. It also sends a nod of respect to the host nation, Scotland, with reflections of the St Andrew's Cross also incorporated in the design.
The Kiwis will face Trinidad and Tobago, India, South Africa and Canada in pool play. The top two teams from each pool then progress to semi-finals ahead of the final game on Sunday 3rd August (NZ time).
The New Zealand Commonwealth Games team now will be complete following the namings of the men's hockey and rugby sevens teams in early July.
The team is expected to number 235 athletes.
