The two accused officials cannot be charged despite the fact police have “no doubt” the crimes occurred because New Zealand has no extradition treaty with Vietnam.
Luxon said the Ministry of Foreign Affairs, Foreign Minister Winston Peters, police and officials had been “doing an investigation”.
“They’ve been meeting with Vietnamese authorities, both police and Foreign Affairs as well,” Luxon said.
Luxon said an extradition was unlikely because of the lack of an extradition treaty.
Police received two complaints in March that a pair of women were indecently assaulted at work, and officers began investigating, district criminal investigations manager Detective Inspector John Van Den Heuvel said.
Police reviewed CCTV footage and spoke to witnesses.
“Police established who our suspects were and that they were Vietnamese officials, visiting on official business. Inquiries were then made with the Vietnamese Embassy who made every effort to assist police with our investigation,” Van Den Heuvel said.
By the time police identified the suspects, they had already left New Zealand.
“As we have no extradition treaty with Vietnam, we were unable to commence extradition proceedings, and as such no charges were laid.”
Police then wrote a letter to be sent through the Ministry of Foreign Affairs and Trade (MFAT) to the Vietnamese ambassador, explaining what had happened and “expressing New Zealand Police’s deep concern over this behaviour”.
Luxon said that there was an ongoing investigation and that,“police are in Vietnam meeting with their counterparts, we have had officials with Foreign Affairs raising the issues as well to understand what actions will be taken domestically within Vietnam.”
“The Ministry of Foreign Affairs and Trade shared those concerns and this was conveyed to the ambassador.”
MFAT confirmed the Vietnamese officials were not entitled to diplomatic immunity, as this only applies to diplomatic staff accredited to New Zealand.
“Police have no doubt these two women were indecently assaulted by two men while working and had these men still been in New Zealand we would have pursued criminal charges,” Van Den Heuvel said.
Police carried out a “thorough investigation” and updated the victims regularly, as well as offering them Victim Support.
“While we know this is not the outcome they would have hoped for, police have exhausted all plausible investigative avenues.”
