A young witness told the Nia Glassie murder trial in Rotorua today wrestling moves practised by adults on children in Nia's home were from a Playstation game.

Murder accused Michael and Wiremu Curtis did not do "pedigrees, tombstones, choke slams and body slamming" before they got the Playstation.

The schoolgirl was being cross-examined by defence lawyers for the five accused over Nia's death through closed circuit television.

Her evidence in chief yesterday was by way of videotaped interviews with a Child, Youth and Family expert.

The child witness agreed with Jonathan Temm, counsel for Michael Curtis, that the wrestling was done on a mattress on the lounge floor and on the couch.

Sometimes it was a game, and sometimes it hurt and she cried.

To Wiremu Curtis' lawyer Craig Horsley, the witness said she would watch the Playstation games with the adults.

Sometimes she and a younger child witness in the trial would wrestle each other for fun while the grown ups watched and laughed.

She never did wrestling moves on three-year-old Nia.

Asked by Mr Horsley if it was supposed to be a game when the men wrestled the children she replied: "I don't know." The witness agreed that if one of the children cried the men would stop.

Harry Edward, representing Michael Pearson, asked if Pearson came to visit the house, saw them playing the game and joined in.

Witness:"Yes." Mr Edward:"It was funsies?" Witness: "Yes."

Cross examination continues after lunch.
