Rochelle Crewe broke her 40-year silence in the Herald in October 2010 to ask police to reopen their investigation to find out who killed her parents, Harvey and Jeannette in 1970.
The request was refused but police bosses agree to conduct a "thorough analysis and assessment of the Crewe homicide file in an endeavour to answer questions raised by Rochelle Crewe".
The review was announced by then Deputy Commissioner Rob Pope shortly afterwards.
A report will also be released today by David Jones QC, who provided independent oversight and assessment of the review.
Harvey and Jeannette Crewe were murdered at their Pukekawa farmhouse in 1970.
Arthur Allan Thomas was found guilty of the murders in 1971 and again at a retrial in 1973. But in 1979, after he had spent nine years in prison, he was granted a pardon on the basis that the police case against him was not proved beyond reasonable doubt.
In 1980, a Royal Commission of Inquiry found that the police planted evidence that was used to wrongly convict Mr Thomas and that the farmer should never have been charged with the murders.
The commission said neither Mr Thomas nor his rifle was involved in the murders, which remain unsolved. He was later paid $950,000 compensation.

1973: Thomas is convicted again at a retrial.
1979: Thomas receives a pardon after an investigation ordered by Prime Minister Robert Muldoon.

2010: Rochelle Crewe breaks her 40-year silence in the Herald to ask police to re-open their investigation to find out who killed her parents.
