Ms Cochrane said Titford kept her as a prisoner and robbed her children of their childhood, repeatedly beating them with a belt, shovel, hammer, fists and a plastic pipe.
Judge Duncan Harvey said Titford's "reign of terror" started at Mangonui Bluff when he raped Ms Cochrane a few months after they got married.
"You blamed your wife, children, police and the Government for conspiring the charges against you. You ruled your family by fear and destroyed any chance of happiness."
Since escaping the violence four years ago, her family had moved each year, struggling on a benefit and begging for food from welfare agencies such as the Salvation Army.
Ms Cochrane said had it not been for the "Violence: It's Not OK" campaign by Women's Refuge, police, the district health board and other Northland social agencies, they would have continued to suffer the abuse.
"It's Not OK" Whangarei spokeswoman Liz Inch was pleased that the campaign had made such a difference as its purpose was to get people who have been living with domestic violence to speak out.
"It will encourage other women, children and men if they are being abused, to seek help," Ms Inch said.
Judge Harvey said it was only right that the country also learnt that Titford's accusation against Maori over land claims, for which he received widespread sympathy, were "baseless".
Titford torched his home and caused other damage to his farm at Mangonui Bluff during a dispute with the Government and blamed it on local iwi, Te Roroa.
Alex Nathan, a Te Roroa kaumatua, said the hapu had not yet met to discuss the news, but he was pleased the truth had finally come out. "It has vindicated us," Mr Nathan said.
