for all purposes associated with the preparation of future fuel excise claims. Where an agent acts on your behalf, payment of the refund of fuel excise duty to an agent extinguishes the entitlement for that refund. The NZ Transport Agency, acting as delegate of the Chief Executive of the Ministry of Transport, will not be a party to any dispute between you and your agent. Appointment of an agent does not remove you from the refund process and the Transport Agency reserves the right to contact you at any time for corroboration of applications filed. This authority remains in place until the Transport Agency is advised otherwise. In the event that you cancel the relationship you have with your agent, you will notify both your agent and the Transport Agency in writing.
