A Kiwi woman living in Brisbane has been jailed for helping clean the flat where a couple were tortured before being shoved into a toolbox and dumped in a creek.

Ngatokoona Mareiti, 40, did not help to kill 28-year-old Cory Breton and 31-year-old Iuliana Triscaru in 2016.

But when she visited the flat they were being kept in to buy drugs, she saw the pair sitting on the couch with their hands tied behind their backs.

The pair were tortured before being forced into a large metal toolbox and dumped in a lagoon in Scrubby Creek in Kingston, reports 7 News.

It's alleged Mareiti heard the pair screaming from inside the toolbox they were forced in to, and did nothing.

Police allege Breton and Triscaru were crammed inside the box and driven to the creek. They were then taken out and shot before their bodies were put back inside and dumped in the water.

Mareiti then bought cleaning products under the direction of her co-accused and scrubbed the unit in which the pair had been held, reports 7 News.

The mother-of-seven has been sentenced to nine years for manslaughter.

She will be eligible for parole in 12 months, and the court heard it is likely she will be deported back to New Zealand.

In the Brisbane Supreme Court on Tuesday, Justice David Boddice said her involvement was "significant".

"It was apparent from the fact they were tied up right from the start this was a dreadful event," he said.

"You did nothing about contacting the authorities. You did nothing about attempting to encourage the others to desist in their conduct," he continued.

"By your dreadful, and what I consider, despicable deeds, you allowed events to unfold that caused the deaths of these two people."
