The pair were arrested in Renall St at about 7.30pm after being tracked by police dogs.
A property owner with a CCTV camera also helped police locate the offenders.
"They've also gone on to a residential property and the property owner happened to have ... cameras on their property which has alerted them to the fact that these boys are there. Police were then able to view that footage which assisted us [with] locating the boys," he said.
Mr Sutton said the pair unlawfully entered two cars in Patea Place and stole property. He was unsure what was taken.
Another member of the public helped police by giving a description of the boys.
"That information that was given just filled that gap to where those boys had gone to. It was a reasonable distance [from where] they'd walked to where they were located."
He said the fact that the cars were left unlocked made it "a lot easier for them".
"Just a reminder to people to make sure they secure their vehicles. Just make it that little bit harder for them."
The boys were taken into police custody and the stolen property was recovered.
They have been referred to Youth Aid again.
