Hawaii does have some extensive laws about importing dogs into the state because they are rabies free. Here is some information from the Hawaii Dept of Agriculture.
"Furthermore, the law requires dogs and cats not meeting all of the specific 5-Day-Or-Less program requirements to be quarantined for
up to 120 days upon arrival In Hawai`i. (See “Hawaii Rabies Quarantine Information Brochure” for details on 120-day quarantine.)"
You will need to check with the state to see what you need to do to get your Yorkie into the state, I think there are ways to circumvent the 120 day quarantine period but you need to get it done early. Here is the website to start with.
