The trial was delayed last year after he sacked his defence counsel Craig Ruane and told the court he wanted to conduct his own defence.
Mr Ruane has been appointed amicus curiae, or friend of the court, to advance legal arguments on Fawcett's behalf during the trial.
A second murder trial, also at the High Court in Christchurch, gets underway tomorrow. Lucille Scollay, 44, will stand trial for the alleged murder of her husband Guy Scollay, 48, at the pair's Christchurch home on February 10 last year.
The trial was also scheduled to start today, but given that it clashed with the anniversary of Mr Scollay's death, it was delayed for 24 hours.
