I'm flying out of Wellington Int'l Airport soon. Can I buy stamps at the airport? And if yes, are they available on Sundays as well?
Quote from the airport's FAQ:
Stamps and some packaging can be purchased from Relay on Level 1. A mail box is located on level 1 of the main terminal building at the top of the escalator near the front doors in the check-in area.
Opening hours for Relay:
4.00am - 8.00pm Sunday - Friday
4.00am - 7.00pm Saturday
