Hi Dion, Mick, I often see leucistic Providence Petrels up here and it 
shouldn't be confused with belly plumage wear commonly seen later in the season 
(August-October) in worn adult birds. We photographed one on the recent sea 
mounts trip which had a broad crescent of pure white feathers in the breast and 
in addition to the normal whitish face feathering had frosty white feathering 
going up further over the head. The most extreme example I've seen was a bird 
in 1998 (can't relocate photos taken at the time) which had the general plumage 
configuration of a Tahiti Petrel, which no way could be attributed to plumage 
wear. As Dion points out Providence Petrels are almost identical in structure 
to Grey-faced Petrels, not at all like Kermadec and even less like Herald. A 
lot of Kermadecs (but not all) can also show a whitish leading edge to the 
inner wing but Herald shows an extensive pale 'flash' down through the 
secondaries. Cheers - Paul.
