It is understood the man grabbed one of the younger boys, but backed off after being threatened by the other youths.
He then followed the alleged offenders through the streets as they threatened him with a real estate sign pulled from a lawn and threw rocks at his car.
Officers arrested all four of the alleged offenders soon afterward.
Detective sergeant Heath Jones said the 11-year-old alleged offender had been put into care in Gisborne last month after taking part in several burglaries.
The "out of control" boy would often walk down streets knocking on doors as he sought empty houses to rob, he said.
"There hasn't been many positives in his life. He's certainly not had many positive role models in his life."
Mr Jones said the 16-year-old boy and girl had appeared in Napier District Court earlier today.
The 11-year-old and the 12-year-old had been placed in secure care by Child, Youth and Family, he said.
