How do I modify my current listing to an auction

Hello Daniel. When you relist the vehicle you choose auction instead of asking price.

Thanks Callum, but I don't see that option. Do I have to Withdraw the listing first?

Oh. When you said it didn't sell I assumed it had closed. You are not able to change between formats when the item is still live. This is because they have different fee structures. So yes, you will have to withdraw and relist as an auction if you want to. But that will mean paying the fee again...... I believe you can contact Trade Me and explain what you want to do so they can process a manual fee refund.

It had closed, well the time expired with no offers. But that option was still not available under re-list.
