HRS §583A-203
When Hawaii can change another state's custody order
This section says when a Hawaii court may change a child custody order made by a court in another state. It can only do so if Hawaii has the right kind of jurisdiction and one of two special conditions is met. Otherwise, it must not modify the other state's order.

The statute, as written — Jurisdiction to modify determination
Except as otherwise provided in section 583A-204, a court of this State shall not modify a child-custody determination made by a court of another state unless a court of this State has jurisdiction to make an initial determination under section 583A-201(a)(1) or (2) and: (1) The court of the other state determines it no longer has exclusive, continuing jurisdiction under section 583A-202 or that a court of this State would be a more convenient forum under section 583A-207; or (2) A court of this State or a court of the other state determines that the child, the child's parents, and any person acting as a parent do not presently reside in the other state.
