Grant Anson, for the Crown, told the jury of seven men and five women that the alleged offences happened between 1987 and 2009 in areas around the Far North and Kaipara.
He said the defendant achieved what he wanted through his display of violence and loss of temper.
Mr Anson alleged that the man burnt down his matrimonial home to gain public sympathy.
The defendant used a number of weapons including a belt, shovel and hose pipe to assault his victims, the Crown alleged.
Defence lawyer John Moroney said the allegations against his client were "contrived" to get money from him.
He said there were never any complaints in the many years the defendant knew the woman.
Judge Harvey declined the defendant bail for the duration of the trial to the address proposed but would revisit the issue if another address was approved by the Crown.
