Another $1.35 million out of the millions donated so far will be given to those affected by the mosque shootings by the end of the month.
This story has been corrected. The original stated an extra $3m would go to victims and their families. The correct figure is $1.35m.
The news comes as a relief for Muslim leaders who say the initial payment of $1.7m has already been spent, leaving some to go in to debt to pay everyday needs such as rent and groceries.
The first tranche of funding saw $5000 given out for each injured person and $15,000 for each of the deceased's families.
More than four weeks on and the money had been spent, leading to questions over why more of the roughly $25m raised so far could not be given to those most in need.
The chairperson of the fundraising committee set up by the Muslim community in NZ, Ahmad Zainuldin, said together they had raised a staggering $6m, mostly made up of thousands of small donations.
It was more than he ever thought was possible.
"Not in a million years. It's overwhelming you know. I mean now we know the whole world is with us. That's very important."
Ahmad Zainuldin said a portion of the money they had raised would be added to some of the funds collected by Victim Support in order to get another $1.35m to those with injured or deceased family members.
Importantly the money would be handed over just before the month of Ramadan, which was traditionally a time of giving for Muslims, he said.
Ramadan was also a time when families came together, which would make it a particularly tough time for those who had lost a loved one.
"I don't think we can imagine how the situation is for them you know. It's such a horrifying thing to happen to anybody.
"So hopefully this will help them a bit. It's a huge gap in their life, a vacuum for them. For example if the father passed away who is going to help their children."
Vice-president of the Pakistan Association, Naema Khan, lost her brother-in-law and her nephew in the Al Noor Mosque attack. She said the extra money to help meet families' immediate needs was desperately needed.
"It's really good news for them," she said. "They can probably provide a decent house to their children.
"They will [be able to] pay their rent, they will be buying their groceries, they don't have to worry about their children's education."
Naema Khan, who had devoted herself to helping some of the widows left behind, said one thing the money would not help with was the mountains of paper work families needed to complete to access ACC or visas for visiting family members.
"The families actually need support and I think they will need it for some time because at the moment things are not really clear and there's a huge communication gap."
At this stage due to privacy concerns, only Victim Support had access to the database of victims and their families.
Ahmad Zainuldin said for now the Muslim community was happy to go through them in order to make sure the money got to where it was needed most.
However, he hoped in the longer term they would be able to help the families directly.
