Interim chairwoman Jeanette Brock said at least $6000 was needed per month to stay afloat.
"We are awaiting word from the Lotteries Commission on our funding application for $70,000 to cover wages and I think we'll get some money from them, not the entire amount.
"There's about $36,000 in our account and with funding from the commission, that should get us through this year," she said.
The association last ran out of funds in 2009 - forcing a part-time employee to look for work elsewhere
The Accident Compensation Corporation (ACC) used to contribute $6000 a year but that stopped in 2009 and since then the association relied on charities to get through on a month-by-month basis. A Givealittle page has also been set up.
It is reported that a person receives a brain injury every 15 minutes.
The injuries are the leading cause of death and disability in New Zealand and can have life-changing results for both the injured person and their family/whānau.
Those wishing to donate can do so via the Givealittle page or deposit money into the association's account: 12-3093-0207556-00.
