The DNA Breakthrough and Victim’s Initiative
The resolution of the 1988 attack was driven by the victim’s own persistence. In 2025, the complainant contacted the police "105" non-emergency line to inquire if forensic swabs taken after her attack still existed. Despite the decades that had passed, police located the original swabs and ran them against the national DNA databank, which became operational in 1996. The results provided a definitive match to Rewa. Detective Inspector Scott Beard noted that in 1988, DNA was not a tool available to investigators, making the preservation of the evidence and the victim's call critical to achieving justice.
Scope of Offending and the 2006 Henwood Report
Rewa is currently serving a life sentence for the 1992 murder of Susan Burdett and preventive detention for sexual attacks on 25 other women. However, a 2006 police report by retired Detective Senior Sergeant Dave Henwood suggests the scale of Rewa's crimes is "chillingly" larger. Henwood’s profiling unit estimated Rewa could be responsible for up to 26 additional sexual attacks that were either never reported or never linked. The report highlights Rewa’s "behavioral uniformity" and geographic reach, suggesting he likely began offending as early as 1975.
Police Launch 1985–1989 DNA Review
In response to this latest conviction, New Zealand Police have initiated a project with PHF Science to re-examine sexual assault cases from 1985 to 1989. Detective Inspector Beard confirmed that the initial focus is on Auckland City files to identify whether other DNA samples might match Rewa’s profile. Beard emphasized that while police cannot turn back the clock, modern forensic techniques offer a unique opportunity to provide closure for victims who have lived with unidentified trauma for decades.
