"I don't agree it was awful football…maybe not attacking football," said Heraf. "There is always a balance between attacking and defending. For this game we had to focus on defence. The only thing that didn't work out was our attacking style."
Former captain Abby Erceg has been prominent in her criticism since the match, equating Heraf's strategy to "cowering in a corner" and confirming his tactical approach was one of the main reasons she retired for the second time.
Heraf said he was unaware of Erceg's comments – curious, given their airplay – but also brushed them off.
"I haven't heard Abby Erceg's comments," said Heraf. "But it's her opinion. A fantastic player, but she made the decision not to join us anymore. We have to accept that and focus on our girls…on who is available and wants to play."
"Last week was a big step. The players were working hard, we have the big goal of going through the group stages, we call it with a clear slogan, we have all our posters in the dining room and meeting room; 'History's possible'."
Heraf was on the front foot on Tuesday, but he had to be after the fallout following Sunday's match.
There was a significant media turnout at NZF's Albany headquarters, and Heraf sat through one on one interviews with all the major news organisations.
The 50-year-old maintained he was the right man for the job, even though it came about in unusual circumstances, as a normal scenario would see the technical director appoint the Ferns' coach.
The former Austrian international is convinced he has the faith and belief of the dressing room, and that his path is the only way, even if there are some painful teething problems at first.
"For sure I am the right one," said Heraf. "I know what I do. When you see it as a modular system, getting piece by piece, we made one step. It didn't help us to win, but it helped us to develop in a certain area, the defending one."
