They want a change in domestic abuse legislation
The friends and family of Lincoln University graduate Grace Millane have launched a campaign aiming to change the law following the trial of the man who murdered her.
She was strangled by a 27 year old she'd met whilst in New Zealand.
He claimed her death was a "sex game gone wrong" but that was rejected in court.
Now Grace's family wants that kind of argument banned as part of a new domestic abuse bill.
