It also aimed to increase understanding around the complexities of families in these situations, and enable agencies to provide a better response to their needs.
Ms Robertson said feedback from the study revealed how time-consuming, complex and costly the process for accessing social support services was.
"This prompted us to reflect on how we could improve the situation," she said.
The City Mission's partnering with other community agencies around Auckland in the operation of food banks was a fundamental transformation.
The food bank at the Nga Whare Waatea marae, and partnership with MUMA, was the first trial of this new initiative, Ms Robertson said.
Muma chief executive Willie Jackson said the food bank would complement the organisation's work in the South Auckland community.
"Muma is the biggest provider of Whanau Ora in South Auckland, serving over 600 families.
"Access to the conveniently located food bank in the centre of Mangere will provide welcome relief for families struggling to make ends meet.
"Our partnership with the City Mission has great potential, and we look forward to a strong and productive relationship," Mr Jackson said.
