Less than 12 hours later, Adam Nauka, a migrant worker, was found dead on the same property.
Both workers were employed in New Zealand under a Recognised Seasonal Employee (RSE) visa, and were visiting on a tourist visa.
Detective Senior Sergeant Paul Wilson announced last night that police had filed a murder charge in place of a simple assault charge relating to the death of the woman.
A Vanuatu country liaison told RNZ Pacific that Nauka passed away as the result of a medical issue.
In court this morning, defence lawyer John Wayne applied for interim name suppression for his client to continue until his scheduled High Court appearance on February 18.
