Tips for First-Time Travelers?

Kia Ora, friends!

My husband and I are celebrating 15 years of marriage by fulfilling our dream of visiting your beautiful country. We are psyched!

We know we need a voltage converter and electric outlet adaptors for our devices, but what are some other things we'll need that are not commonly thought of?

Also any tips and advice for making the most of our trip is much-appreciated! We'll be arriving in Auckland and making our way south down both islands to Queenstown over two weeks.

TIA!
