Eighty-seven people turned up at Christchurch Hospital yesterday after the massacre across two mosques in the city, and three others presented at other community clinics.
Last night there were 17 people unidentified. It is understood that through the night more people had been identified and that number had been reduced to 6.
The man said he had been told the people could not be identified because of tubes in their noses and mouths.
"We are hoping she is one of them."
The main shooter has been identified by Australian police as Brenton Tarrant — a white, 28-year-old Australian-born man, who uploaded to his Twitter account, before the shooting, a manifesto explaining his intentions.
Two of the three other people apprehended yesterday remain in custody.
The fourth person was found armed at the scene but didn't appear to have had anything to do with the killings.
A large police presence remains in Christchurch, and a heightened police presence can be expected at community events nationwide for safety and reassurance.
