A Melbourne woman has confessed to the manslaughter of a man whose body was found weeks later in a paddock in Melbourne's southeast. 

Nicole Anderson was initially charged with murder over the death of 26-year-old Zane Meyer at Oakleigh sometime between May 11 and 13 to which she pleaded not guilty. 

On Thursday she pleaded guilty to the lesser charge of manslaughter in Victoria's Supreme Court, speaking only to confirm she could hear proceedings and to enter her plea. 

Meyer was reported missing before his remains were found at a Lysterfield paddock in June 2020, weeks after he vanished. 

Anderson, 38, has been charged alongside two co-accused, Trent Pearson and Jaryd Kemp. 

The three accused have each pleaded not guilty to one count of murder and have been behind bars for more than 18 months awaiting trial. 

Meyer, a Kiwi native whose family still reside in New Zealand, was last heard from on May 11, 2020, sparking serious concerns for his safety. 

He was believed to be living in Cheltenham when he disappeared and also went by the name Rànbow Treè. 

The matter will return to court on March 18 for a plea hearing.
