The correct answer is - Polynesians.
The Lapita were a people that migrated into Oceania from the Southeast Asia region. They branched off into two cultural groups, one of them gave rise to the Maori, while the other one to the Polynesians. The Maori were the smaller group that migrated and inhabited the islands of New Zealand, while the Polynesians migrated and inhabited the Polynesian islands. Because of the isolation of the two groups they developed unique cultural traits in time, and even though they had the same root, the changes and different development of their cultures is very evident.
