But at the High Court at Whangārei on Friday, his lawyer was instructed to enter a not guilty plea.
The court, full of family and friends of Chapman, heard how Johnstone was released from hospital this week and is now being held at Mt Eden Corrections Facility.
Grbavac indicated Corrections was struggling to correctly manage Johnstone’s injuries and his client was seeking bail.
A previous application for name suppression was abandoned, with Johnstone’s name suppression lapsing on Friday.
His appearance in court was again excused on Friday, but he was ordered to appear either in person or by video link at his next appearance to confirm the not-guilty plea.
Johnstone is due to next appear in the High Court on June 4, with a trial date set for early 2027.
Chapman has been remembered by her three sons as a “beloved mother” and “precious taonga”. Her friends describe her as a beautiful person, who was mischievous and fun.
