Competition from other charities also affected the food bank, she said.
High rents, unexpected bills, children left unexpectedly in a family member's care, and job loss were among the most common reasons people gave for accessing the service.
"Some of the single ones on benefits, by the time they have paid their rent they only have between $14 and $17 left for food."
Ms Matoe said the "vast majority" of cases were in genuine need and those that were "pulling your leg" were easy to identify. People accessing the food bank more than once were diverted to other Salvation Army services like budgeting and counselling.
"It takes a lot for people to come in. A lot of people have already been to [Work and Income]. There's people that don't come that really should because they think there are people worse off or because of pride."
The average food parcel comprised bread, milk, eggs, tinned goods, toilet paper and other items like fresh fruit and vegetables, according to availability. Ms Matoe said when there was little food, it affected the nutritional value of the packages she could give out.
"I did not know what we were going to do today ... I am going to spend today sitting on the phone," she told the Advocate.
