Season the pork chunks generously with Hawaiian sea salt.
Place 2–3 taro leaves flat, and add a portion of pork in the center. Fold the leaves around the meat into a tight bundle.
Wrap the taro bundle in a ti leaf (or banana leaf), folding securely. Tie with kitchen twine to hold in place. Repeat for remaining bundles.
Place the lau lau in a slow cooker with 2–3 cups of water. Cover and steam on low for 4–5 hours, until the pork is tender and the leaves are soft.
Remove the outer ti or banana leaves before serving. Eat hot with poi, rice, or vegetables.
