Yes, you're right.  Fiji was home to at least two large, flightless galliforms: 
_Megavitiornis altirostris_ and _Megapodius amissus_.  Both were megapodes 
(Megapodiidae).  _Megavitiornis_ was apparently highly convergent on 
_Diatryma_, although not as large.

That's certainly the case for _Sylviornis_ and _Megavitiornis_.
