Mark Hager has apologised to members of the Black Sticks women's hockey team, after inadvertently emailing them criticism of their attitude.
Hager, who has coached New Zealand for a decade, admitted sending an email to his players that was intended for team management during the World Cup in July.
The 54-year-old singled out several "struggling" players, all of which saw a copy of the email.
He expressed frustration at several players' work ethic and training habits.
A Hockey New Zealand statement said he had taken full responsibility and apologised to his players.
Chief executive Ian Francis said no further action would be taken, as the matter had been resolved quickly and within the team confines.
"The matter was dealt with immediately by the senior player leadership team and the coach Mark Hager, who took full responsibility for the incident," the Hockey NZ statement said.
Hager is yet to comment about the situation
The Black Sticks finished a disappointing 11th at the World Cup, three months after snaring gold at the Commonwealth Games.
