The family of a New Zealand-raised businessman murdered in Bali are demanding a "proper investigation" into his death.
Robert Kevin Ellis, 60, was murdered in the villa he shared with Julaikah Noor Aini, also known as Noor Ellis, in Bali on Monday last week. She was arrested the next day after Mr Ellis' body was found wrapped in plastic and a bed sheet, and dumped in a rice paddy 25km away.
Police are considering charging her with premeditated murder, and allege she paid a group of men and her housemaids to murder Mr Ellis and dispose of his remains.
Today his family released a statement saying they are "growing increasingly concerned at the lack of information" they have received from Indonesian authorities, and the handling of the investigation.
Ms Ellis' son, Kelvin, said he had returned from Bali frustrated at the lack of information.
"We've received no communication from them. We found out about it all on the internet," he said in the family statement.
"I got to Bali to find out that the accused has been given access to the crime scene a number of times, even after confessing. This isn't the right way to do things. It isn't being handled in a professional or just way."
Kelvin said his family were focusing on the funeral and supporting each other.
"But the family is united in seeking justice. Right now we are concerned that we won't get it," he said.
"We're asking MFat and the government to get involved on behalf of the New Zealand relatives to ask the Indonesian government to make sure a proper investigation is conducted."
Mr Ellis was born in the UK but his parents, Nancy and Bob, moved him and his three siblings to New Zealand when he was a child.
He was raised in South Auckland and later moved to Australia. He met Aini in 1986 and the couple married in 1989 and had two sons, John and Peter. Mr Ellis also has a son Kelvin and daughter Christina from a previous relationship.
His parents told the Herald they were devastated by his death.
Mrs Ellis said she did not know much about what had happened. She was leaving that side of things to the family and was focusing on her son.
"He was a rock. He was a marvellous son," she said.
"He was so good to all of his family, he looked after everybody - including the one who [allegedly] did the damage."
"It's bloody awful to be honest ... but it's done," father Bob Ellis said. "We've accepted it, it happened. His body is coming home."
