A speech made in both English and Māori remembered him as a loved husband, father, grandfather and a man of principle.
The burial closed with a song and a prayer.
Former Labour list MP Dover Samuels was among the mourners. He shared a stories about his time fishing with Anderton and their friendship.
About 100 people gathered at the cemetery.
It is where his mother is buried and where he spent many years as a child, family friend Josie Pagani said.
"There's a big family connection here.
"He was very much an Aucklander and an adopted Cantabrian."
Pagani, who worked in Anderton's office while he was a Labour poltician, said it was fitting to have a public funeral in Christchurch and a smaller gathering of friends, family and political associates in Auckland.
"It's a time for family and those who really loved Jim as a husband, a friend and a mentor," she said.
