A woman has appeared in court, charged with the manslaughter of Hamilton man Sao Young.

Young, 40, was last seen on the evening of March 12 in Hamilton's Insoll Ave area and police believe it was on that night he was killed.

After he was killed, his body was then allegedly taken to a rural property in Ballard Rd in Gordonton, where it was discovered by a farmer, nearly a month later on April 13.

The 34-year-old woman appeared in the Hamilton District Court on Friday. She faces two charges: one of kidnapping Young, and one that she caused his death by an unlawful act, namely assault, and thereby committed manslaughter.

Judge Jane Lovell-Smith granted her name suppression and remanded her to next appear in the High Court in Hamilton on October 6.

Two others are facing charges in relation to Young's death: A 20-year-old woman appeared in Hamilton District Court on Thursday charged with being an accessory after the fact to murder.

She also faces two charges of kidnapping and a further two charges of wounding with intent to cause grievous bodily harm.

And a 24-year-old man appeared in court charged with Young's murder. They have also both been granted name suppression and will next appear in the High Court on October 6.
