The trial for the alleged Christchurch gunman could be moved out of the city, and could be pushed back by up to four weeks.
The accused, Brenton Harrison Tarrant, was not present in the Christchurch High Court on Thursday - excused because of the brief and administrative nature of the hearing.
Content of Thursday's hearing is unable to be reported or made public for legal reasons.
Justice Cameron Mander confirmed, however, the Crown is in discussions to push Tarrant's May 4 trial date back by up to four weeks.

The defence counsel of Shane Tait and Jonathan Hudson has applied in the Christchurch High Court to change the venue, which will be discussed in October.
Tarrant faces 51 charges of murder, 40 of attempted murder and one charge under the Terrorism Suppression Act, following the March massacre at two mosques in Christchurch.
More than 40 people were in the public gallery for Thursday's proceedings.
Advisers are continuing to help family and survivors understand the legal process as it happens - with up to 15 languages spoken among the vicitms.
Tarrant has been remanded to a pre-trial callover on October 3.
