Beware of the afterhours charges that Jucy charge.
You will pay for at least 5 days hire (even if your booking confirmation is for 3 days). Also you will pay $30 for them to drop the car off at the airport after hours.
You will then pay an extra $30 (max) for parking at the Auckland Airport.
This is not obvious from their booking mails but you should take this into account when doing your comparisons with other firms.
