Would Samoa be an over-wintering site for Golden Plovers?

Following on from my previous post, we saw a lot of golden plovers on Samoa, where they tended to hang out on mown lawns.

They all seemed to be in non-breeding plumage, which seemed to be a bit strange at the end of September. Is Samoa on the East Asian flyway? (It is to the east of 95% of the dateline).

My question is whether Samoa a place where golden plovers hangout when they are siting out the northern hemisphere breeding season?
