Rajiv Bhujun will be questioned by detectives in the new inquiry into the 27-year-old's death.
It is understood Mr Bhujun opened the door of the hotel room for John McAreavey when the Co Down man discovered his wife dead in the bathroom of their suite, while on honeymoon in January 2011.
Mr Bhujun's colleagues Avinash Treebhoowoon and Sandip Moneea were accused of murdering the only daughter of Tyrone GAA boss Mickey Harte and stood trial.
When called give evidence against the pair, Mr Bhujun could not be found and it is believed he was working abroad on a cruise ship.
Treebhoowoon and Moneea were found not guilty of the murder, following an eight week trial on the island.
A fresh investigation, led by three senior Mauritian police officers, into Mrs McAreavey's murder was set up in the days after the court case.
A judicial inquiry has been launched to find out what can be done to bring the perpetrators to justice, and Northern Ireland's Attorney General is also to examine papers from the trial.
