The 50-year-old had been on special leave since June after New Zealand Football received a letter from the Players Association with complaints from Football Ferns players. 

Heraf was appointed as the Technical Director in April 2017 and took over the Football Ferns Head Coach role in December. While an issue was raised by a player after their tour of Spain, it wasn't until their friendly match with Japan that the issues came to public knowledge.

Former captain and New Zeland's most capped player ever, Abby Erceg decided to enter into retirement once again, citing it was a result of Heraf's tactical approach, while former Football Fern Katie Duncan told Stuff.co.nz in June: "He needs to go."

Heraf told the derStandard.at  last month: "The players oppose my European style, with high standards and high expectations of professionalism, and prefer a fun and family culture with a focus on making fun videos and opening up to social networking."

There were allegations of bullying from anonymous players in the NZ media, but Heraf said the allegations were "out of thin air" and insisted he had documents that would clear him.

Andy Martin resigned as NZF chief executive in June after facing heavy scrutiny for his handling of the complaints around Heraf.

Heraf will still take part in the current Independent Review into the culture of New Zealand Football.

"Part of the resignation is that Andreas has confirmed that he will fully participate in the review and we will look to the findings of the review to determine the outcomes around this matter," said New Zealand Football President Deryck Shaw. 

New Zealand Football will begin the search for a new Technical Director and Football Ferns Head Coach at the conclusion of the Independent Review.
