Are there any large lakes in Polynesia? The Māori, Hawaiians, etc are one group of people I would expect to make a distinction between lakes (puddles, really) and open ocean.

Yes, there are many substantial ones in New Zealand. Lake Taupo is a substantial one, and there are some large ones in Otago and Southland which are not abutting the sea.

I would imagine Polynesian languages would distinguish between fresh water bodies and salt water ones, since they need to be able to drink. Even small islands can have pools.
