Her ex-boyfriend, who is a graduate from the University of Essex, also made a statement at Auckland High Court.

He said the pair always used a system of safe words and signals to make sure Grace was never in danger or hurt.

He said: "When we researched it we knew the word was asphyxiation. Grace and I discussed keeping hands wide and on the side of the neck, never on the front.

"Grace and I would have a safe word most of the time which we had discussed, something like 'turtle' or something ridiculous.

"Grace and I used a tapping practice too. If Grace tapped me three times then it would stop.

"Grace would tap out maybe one in four times. Grace would be sure to do this and I trusted that anytime it was too much for Grace she would do this.

"Grace and I were careful to discuss not only the physical but the psychological aspects to practising BDSM."

Defence barrister, Ron Mansfield, told the jury: "All the evidence shows that Miss Millane was a loving, bright, intelligent young woman and she was.

"That is her reputation and that should be her reputation and her memory at the start of this trial and at the conclusion if it.

"The fact that we need to discuss with you what she liked to do in the bedroom should have no impact on he reputation at all.

He ran an internet search for the "Waitakere Ranges", a chain of hills in the Auckland region where Grace's body was eventually found, the "hottest fire", watched porn as well as taking photos of Millane as she lay on the floor of his bedroom after she died.

Later that morning, he confirmed another Tinder date for later that day, bought cleaning products and a suitcase. He hired a carpet cleaning machine and a rental car.

Her body was crammed inside a suitcase buried in scrubland outside the city.
