What prevented the lapita, polynesians, and others from developing an empire in oceania and nearby regions of the world?

Geography and political organization.

Explanation:

The Lapita culture settled in many of the islands of Polynesia establishing villages with no other intention than farming, breeding and living  based on their culture. They never organized under the concept of settig a more organized and bigger order like a captial or state-city, in fact they were sea explores looking for opportunities to live accross the Polynesia, but never as conquerors as they never built military forces to consider being a threat for other civilizations.

Maybe if the Lapitas had established in Australia, things would have been different, but  the chose small islands which was also a limitating factor for them to grown as an empire.
