The Crown has been granted an extension to file police evidence in the Carmen Thomas case, saying it will not be until next year before it can present more than 80 sworn statements.
Bradford Callaghan, a former partner of Ms Thomas and the father to her five-year-old son, is charged with her murder.
He appeared in the Auckland District Court on Tuesday via a video link from prison.
Mr Callaghan was arrested in September, almost three months after the 32-year-old Auckland woman went missing.
Police believe Ms Thomas' body was dismembered before being buried in the Waitakere Ranges.
A post-mortem has been completed but police are not discussing the results.
Crown prosecutor Simon Moore, QC, told the court on Tuesday the Crown has at least 80 sworn statements and more are likely to be presented.
Mr Moore says investigations will continue for some months.
Mr Callaghan's lawyer does not object to the extension, but told the court his client reserves the right to apply for bail at any time.
Mr Callaghan will reappear in court in February.
