Must-see places in New Zealand for a two-week trip

I'm planning a two-week trip to New Zealand and would appreciate some recommendations on must-see attractions. I've heard so much about the beautiful scenery and colorful culture, but attempting to squeeze everything in such a short period of time is stressful. Also, since I'm juggling trip plans and studies, I was wondering if anyone has any advice on how to manage both. For example, how do you manage sightseeing with academic responsibilities? Have you ever used a [buy dissertation service](https://thedissertationhelp.co.uk/buy-dissertation/) while traveling? If so, how did it turn out for you? Any advice for creating the best of both worlds would be much appreciated.
