Several long-standing Silver Ferns are in danger of missing out on the World Cup if they don't perform strongly at trials this week.
Waimarama Taumaunu will name her 12-strong squad for the Sydney tournament on Thursday following three days of trials in Auckland.
The Ferns coach and her fellow selectors have some tough calls ahead, with questions persisting over the form of a number of the team's veterans after a disappointing 2014 international season.
Having won the past nine meetings against New Zealand, it is clear the Diamonds have the wood over New Zealand who, with the exception of the retirement of shooter Irene van Dyk, have remained relatively settled in recent years.
Given Australia's dominance, Taumaunu said players can no longer rely on their reputations to get them picked.
