This word is commonly used for small holes, especially in the context of natural formations like holes in rocks or coral reefs.
For larger holes or openings, you could use lua which means "pit" or "cave".
Here are some examples of how to use "puka" in a sentence:
* He saw a puka in the wall. (He saw a hole in the wall.)
* The ocean water flowed through the pukas in the reef. (The ocean water flowed through the holes in the reef.)
