Easter Celebrations in Fiji

Hi guys,
First time posting.
I'm looking to spend some time in Fiji over the Easter break and I want to experience some of the religious festivals going on in the country. I heard that there is a ritual where they float a cross between some islands but I don't know where this event is happening.

That said, I'm up to experience any cultural Easter event in Fiji be it a parade, stations of the cross or whatever. If anyone has any recommendations on where to go, I would greatly appreciate it.

Many thanks.

There will be lots of great singing in all of the larger Christian churches, even the smaller ones.
Services can last many hours and the Methodist ones will include a good serve of fire and brimstone..

Cheers,
Peter
