John is absolutely right. All snakes are prohibited in Hawaii with the exception of a few male zoo specimens.

"A person can be fined up to $200,000 for being caught importing or owning snakes of any type, but people are encouraged to turn them in under the state’s amnesty program, which provides immunity from prosecution. Illegal animals may be turned in to any HDOA office, the Honolulu Zoo or any humane society with no questions asked and no fines assessed. Anyone with information on illegal animals should call the plant quarantine branch at 832-0566 or the pest hotline at 586-PEST. Animals turned in under amnesty will not be killed. The Honolulu Zoo sends the animals to mainland zoos and educational institutions.
