"We are very disappointed to be in a position where some of the players from within the Football Ferns have felt the need to formally lodge a complaint with NZ Football and would like to thank them for coming forward," said New Zealand Football President Deryck Shaw.
"We hold player welfare as a matter of utmost importance and that is why we are conducting a thorough, independent review. We want to ensure we better understand these issues in an objective review. There is no place for inappropriate behaviour of any kind with New Zealand Football.
"New Zealand Football has clear policies and procedures to protect the welfare of staff and players. We are focused on creating an environment which gives the Football Ferns, and all of our national teams, the best chance of winning on the world stage."
The review will commence this week with the appointment of the independent investigator. The terms of reference under which the investigator is engaged, and the individual appointed to conduct the investigation, will be signed off by the NZPFA.
