More than 50 people are in managed isolation at New Zealand's border facilities so they can attend the sentencing of the Christchurch gunman.
Thirty-four of them are victims.
Among the others, thirteen are support people and one is a minor travelling with family.
Brenton Tarrant is set to be sentenced on 24 August, having pleaded guilty to 51 charges of murder, 40 of attempted murder and one under the Terrorism Suppression Act in March.
The minister in charge of isolation facilities, Megan Woods told RNZ political editor, Jane Patterson, people had travelled from multiple countries for the court date.
