Division of Motor Vehicles & Licensing - DMV
The above is a link to the DMV wait timetables for all locations. The DMV in Kihei is located on 303 E Lipoa St, right next to the aquatic center. You can check in with your mobile phone number and explain the reason for your visit. You will receive updates via text message until it's your turn. Works great!

False Alarm Reduction Program / County of Maui
The "False Alarm Reduction Program" was initiated by the County of Maui to substantially reduce the number of false alarms, that the Maui Police Department has to respond to. Here is the official link to the County of Maui website with further explanations to the "False Alarm Reduction Program". If your home is equipped with a monitoring system that is directly connected to the Maui Police Department, you must establish an account and register your system with the "Cry Wolf Services" website via their secure online registration. In fact, the Maui Alarm Ordinance requires that all alarms are registered on the CryWolf's website.

Maui Bread Company - Open from 7:00AM to 1:00PM, closed on Wednesday and Thursday. Located in the Dolphin Plaza in South Kihei. Phone number and address are on the website. There are some good bakeries on the island, but Christine & Stephan are offering "the real German stuff". They are selling out fast, I suggest you visit them early! The cold coconut coffee drink is amazing.
Im Februar 2022 hat das ZDF in Deutschland eine tolle Dokumentation von der Maui Bread Company mit Christine & Stephan ausgestrahlt. Die haben echte Brezeln und Croissants, Laugenstangen, verschiedene richtige Brötchen und ganz tolles Brot. Für mich ist es wirklich "ein Stückchen zu Hause" auf Maui.
