Corrections chief executive Ray Smith said he wouldn't make the complete review public due to security and privacy reasons.
Corrections' chief custodial officer Neil Beales has made 13 recommendations for changes to temporary releases after the incident.
Mr Beales recommended GPS monitoring would be the default precaution for all prisoners on temporary release.
Corrections chief executive Ray Smith said Smith should not have been considered for temporary release, even though he was eligible.
"Smith is part of a small but challenging group of offenders who are focused on beating the system," Mr Smith said.
"We have on average about 4700 temporary releases each year and Smith has exposed faults in our release process which are being addressed with urgency.
"As well as our review I am working with our justice sector partners and Customs to ensure we share information to thwart these types of prisoners breaking the law."
He said he apologised to Smith's victims and offered to meet with them.
Smith was released for a 74-hour temporary release from Springhill Correctional Facility on November 6. He left the supervision of his approved sponsor and boarded a flight to Chile at Auckland International Airport that afternoon.
He was caught a week later in Brazil and arrested. He is due to be returned to New Zealand before December 1.
