Its going to be a lot different than you expect it to be. You might go through moments of homesickness or even culture shock(depending on where you come from), but it would not last for too long. The key is to be open to the new culture, people and experiences. Also remember you're studying abroad(emphasis on the studying), so choose your classes wisely and plan your time as well. I would not advise taking any upper level classes, except you absolutely need to, the difference in educational systems can totally throw you off your game.
Overall, it is an amazing experience.

Hi Jess,
Thanks for your positive feedback.
Great to hear that you are enjoying the time here.
All University staff have an individual personal email attached to their team email. You only need to remember 'studyabroad@auckland.ac.nz' (easy to remember) to contact the Study Abroad team.
Hope you have a great time for the rest of your time here.
All the bests,
Sarah
