Service was pretty good overall.

No waiting around at all – just show up and pick up the car right away.

The staff at the counter were super friendly and even upgraded us to a bigger car for free.

Picked up the car right inside the airport. During the process they asked if I was familiar with New Zealand road rules and whether I’d be driving on toll roads like those north of Auckland. They saw I only had basic insurance and asked once if I wanted to add more; after I said no, they didn’t push it at all. The whole pickup was quick and smooth.
They gave me an MX-5 hardtop convertible, which was an absolute joy to drive. I was really happy with the car. The only downside is the trunk can’t fit a large suitcase, so if you’re booking this model, check the luggage capacity beforehand. The roof opens and closes very quickly, which is super handy.
Returning the car was in the same parking area as pickup. Just follow Google Maps and the road signs and you’ll find it easily – very convenient.
