I've just watched the release video. Here are the obverse themes of the new coins:
5c Bicolor foxface rabbitfish.
10c Fiji Flying fox (bat).
20c Kadavu (crimson) shining parrot
50c Humphead wrasse (fish)
$1 Banded iguana
$2 Peregrine falcon ("The Islander", a subspecies found only in Fiji).
These names are all given in the local language on the coins. Interestingly, the reverse designs of the coins stay AS THEY WERE. Since the 2 dollar coin is new, the tanoa from the old 1 cent coin has been used on the reverse of this design.
The report in a prior post that the Fijian coat of arms would be used is therefore false.
To watch the video stream, click on the link and fast forward to around 56 minutes in to avoid the opening speeches and just watch the video about the banknote and coin designs:
