HRS §431:10-226
How insurers can renew or extend a policy
An insurance company can choose to renew or extend a policy that ends on a set date, even if it wasn't originally renewable. They can do this using a certificate or an endorsement on the current policy, and they don't have to issue a new policy.
The statute, as written — Renewal of policy; new policy not required
At the option of the insurer, any insurance policy terminating at a specified expiration date and not otherwise renewable, may be renewed or extended, upon a currently authorized policy form and at the premium rate then required for a specific additional period or periods by a certificate or by endorsement of the policy. The issuance of a new policy is not required.
