Most of the boxes of almonds had been recovered, along with the trailer and a stolen car.
The goods were expected to be handed back to the chief executive of the foodbank later this evening.
Grant said it would be a sweet moment giving the treats back to the charity.
"It's great we were able to help this charity get the goods back so they can continue to help people and communities in need.
"It's a great result and very rewarding to be able to get back the goods and give them back to the foodbank."
A man, who had a warrant to arrest for an unrelated matter, was taken in custody. He is due to appear in the Manukau District Court tomorrow.
