World Rugby admits the high turnover of senior staff at the Fiji Rugby Union is a cause for concern.
Radrodro Tabulevu announced his resignation as Fiji Rugby CEO last month after just 15 months in the job.
He was the fifth person to have filled the position on a permanent or temporary basis in the past four and a half years, but rejected suggestions he was forced to resign.
World Rugby's Regional General Manager for Asia/Oceania, William Glenwright, says it's not an ideal situation.
"That's something that we've raised with the Union and we've met with them formally on, both during Rugby World Cup and since in visits to the country. They're aware of our concerns and, to be fair to the Union, they share them as well. It's not an ideal situation and not one that either the Fiji Rugby Union or World Rugby aspire to. That is something that we need to address and that's something that we are working with the Union on in a collaborative manner. Our focus at the moment is on creating a robust selection criteria for a replacement CEO".
