Coupfourpointfive has been told the interim regime will downgrade the Fiji High Commission in Wellington to a Consulate.
The Acting High Commissioner, former senior police officer Ponsami Chetty, has already left the office so he can be replaced.
Chetty was ordered back to Fiji but sources say he and his wife have taken off to Australia.
Chetty took up the position in Wellington after Cama Tuiloma was deported, in a tit-for-tat diplomatic action, after the regime expelled the acting High Commissioner for New Zealand Caroline McDonald last year.
Tuiloma is now a permanent secretary for the regime.
In June 2007, the regime expelled outspoken New Zealand High Commissioner Michael Green, accusing him of meddling in the internal affairs of Fiji.
Since the 4th military coup, the interim regime has also expelled three expatriate publishers - two from Fiji Times and one from Fiji Sun.
The five expulsions and deportations exceed the actions of the interim regime after the 1987 military coups.
In October 1989, the then regime of Ratu Sir Kamisese Mara expelled no-nonsense Indian Ambassador Thettalil Sreenivasan after his public comments following the arson attacks on four Indian places of worship in Lautoka. He was given 72 hours to leave Fiji.
In May 1990, Sreenivasan's successor Vidya Soni and his Indian expatriate officers were expelled and given 14 days to leave Fiji after his strong speech at the Sangam convention a few weeks earlier.
