From the website

Maui Humane Society’s mission is to protect and save the lives of Maui’s animals, accepting all in need, educating the community, and inspiring respect and compassion towards all animals.

The humane society is very active on Maui right now and they are helping wherever they can. 100% trustworthy and local. I will post two links. One is for direct donations on their website (credit card and PayPal), one for the giving block for crypto and stocks and the last one is from Pledge.to, where you have a very big range of options to donate.
