The process has started for the Black Ferns as they seek to annex a fifth Rugby World Cup title in August.
A 51-strong training squad has been named and will be part of a regional training programme designed to identify and develop the best players in the country.
In 2016, the Black Ferns were unbeaten in both their home series against Australia, and away series against Canada, England and Ireland.
Black Ferns coach Glenn Moore said the Women's Rugby World Cup in Ireland and Northern Ireland was the main focus for 2017.
"We'll be making World Cup selections from this wider training group. With an Olympic medal-winning sevens team and a growing provincial tournament, there's a lot of talent out there and the number of women with the black jersey in their sights is on the rise. We want to make sure we take the strongest squad possible to the World Cup."
