Prime Minister Jacinda Ardern said the Defence Force "didn't share what was required" in response to allegations published in the book Hit & Run earlier this year.
Ms Ardern said the Government will be speaking to the Defence Force about the allegations after Labour expressed "strong concerns" while in Opposition.
Hit & Run, by investigative journalists Nicky Hager and Jon Stephenson, alleges six civilians were killed and 15 were injured in the New Zealand-led raid 'Operation Burnham' in 2010.
Ms Ardern said after the release of the book "We expressed strong concerns. That's something I hope to engage with Defence over that issue, we said that was an opportunity we would take up when we were in office."
The United Nations Committee Against Torture called on the New Zealand Government to fully investigate the 2010 Afghan raid in June, as part of a list of issues to be responded to by 2019.
"We shared the view that we certainly needed to look into that further, we shared a view that Defence didn't share what was required at the time," Ms Ardern said.
"Now that we're in the position to work more closely with Defence we'll be doing that."
The New Zealand Defence Force has repeatedly denied the allegations in Hit & Run.
