The Black Ferns coaching job is to become fulltime with Glenn Moore being re-appointed to the role through to the 2021 Rugby World Cup.
Moore has held the position since 2015 having taken the side to world cup success in 2017 and enjoyed 23 wins from 26 matches.
New Zealand will host the 2021 world cup with all matches being played in Auckland and Whangarei.
"To play in a world cup at home is special. We know as current world champions we have a target on our back and it's an exciting time to be involved," he said.
"Over the past couple of years there's been massive growth in the top end of the women's game. Our talent pool is deeper than it's ever been so players are working hard to secure a black jersey and have a desire to get better. As a coach that's exactly what you want."
Moore said his new full-time role will allow him to spend more time with players outside of the team environment.
"It means I can help players improve their training and skills by providing feedback throughout the year. We'll be able to prepare in a much more consistent way and take things a step up," he said.
New Zealand Rugby's Head of Women's Rugby Cate Sexton said Moore has "been instrumental in developing the culture of the Black Ferns and steering the team into the semi-professional era.
"He brings stability to our programme during a period of rapid growth and when we have a massive challenge ahead of us in hosting a Rugby World Cup."
Aside from coaching the top team, Moore's role would also include a focus on talent identification.
