"The key thing is New Zealand Government is responsible for the actions of New Zealand troops."
New Zealand troops were on the ground during the mission, and Mr Coleman had been briefed that no civilians had been harmed by ground troops.
The US military was using helicopter gunships during the raid.
Mr Coleman said "you probably can't rule out" civilian deaths from these gunships' fire.
The raid took place two weeks after New Zealand soldier Timothy O'Donnell was killed in Bamiyan Province, and it was seen by some as a counter-attack or a revenge mission on behalf of New Zealand's military.
Government has maintained it was carrying out its security duties in the region.
Mr Coleman this morning rejected the suggestion that civilians had been killed in New Zealand's name.
The mission took place in Talah wa Barfak District, in a province which bordered Bamiyan Province, where New Zealand's Provincial Reconstruction Team was based.
It involved New Zealand's elite SAS troops, which were usually based in Kabul.
Nine insurgents were killed in the strike.
The district's governor initially said there were eight civilian casualties, and a Nato investigation later revealed a malfunctioning gunsight on a coalition helicopter that had resulted in errant shots hitting a building. The building was struck mistakenly, but was previously used as a base for insurgent operations.
The Native Affairs report was conducted by journalist Jon Stephenson. Villagers told him that there were no insurgents in the village at the time of the early morning raid.
Mr Stephenson told TV3: "They told us their stories, which were that six people were killed - including a three-year-old girl - and that 15 were wounded, and they showed us cellphone footage of the dead. They presented us with a government death certificate.
"I did a lot of other investigation and confirmed from very senior Afghan officials, and from people like hospital directors and NGOs, that those accounts were accurate."
Mr Coleman said he disagreed with many aspects of the report.
