Aloha, Sir,
We were taught the relationship between Kamapua'a and Pele is one that was extremely passionate and then volatile. Here is a short version of their story:

This link a very good (extensive document, dated 1891) writing of the history between the two. This is the closest I could find to what we were told by our kupuna:

We were taught when taking pork (cooked or raw) in your vehicle, especially at night, we always wrapped a ti leaf around it. Bringing pork into "Pele's aina" was taunting her, since they had an agreement that Kamapua'a would stay on his side of the island.
As an aside, some of our nephews swear they have seen Kamapua'a in Puna while hunting. A supposedly enormous pig, that cannot be caught, disappears quickly when seen, and dogs will not chase this one
at all. Some of them feel "funny kine" when hunting in certain areas, because it feels like Kamapua'a is watching them. He better
not be over here on Tutu Pele's turf!
All I know is I don't take kalua pig in my car without my ti leaf. Ever. FWIW.
My aloha to your lovely wife, please. Be safe.
JMO.
