In 2014, she had time off work because she broke both ankles in an accident and subsequently could not pay off loans she had taken out in the country, the Givealittle page said.
It is not known what the loans were for. Morehu's family said she owed $40,000 to $50,000. She was unable to secure new work because of the outstanding police cases and she was in a battle with her insurance company over her income insurance.
The details around her arrest and detention could not be verified. Ruby Pitiroi, who is Morehu's niece and set up the Givealittle page, did not return requests for comment.
The Givealittle page said Morehu had heart problems and the family was concerned about her health in jail.
"We spoke briefly with her while she was waiting to be transferred to her permanent prison.
"She was fearful that she wouldn't survive the harsh conditions in prison with her heart complications and pleaded with us to find a way to bring her home.
"She is physically weak and her spirit is broken. We fear for her life in a foreign country that she cannot leave until her debt is settled."
The UAE has strict laws on unpaid loans, which can be considered a criminal offence punishable by jail time.

People could face long periods of detention before trial and deportation, MFAT said on its website.
