Police have confirmed a body found at a South Auckland farm is that of a missing Hamilton woman.
Rae Portman, who was 33, was two months pregnant when she disappeared in June this year.
A body was found at the farm near Papakura on Thursday night.
Some of Ms Portman's personal items were also found at the property, including items of clothing.
A post-mortem examination has been completed, but police do not expect the results to be released for a few days.
A 32-year-old man has already appeared in the Papakura District Court charged with kidnapping Ms Portman.
Detective Inspector Mark Gutry, who is leading the investigation, says more arrests are likely but not until after the weekend.
