3 weeks in October. Second time traveling both islands.
Want to do this trip a bit easier.
One week in the N island. Rotorua for a week? Sights around?
2 weeks in the S island. Unsure where to base x2 weeks.
I think your question may not be specific enough. It would be helpful to know where you have already been that you don’t feel a need to return to.
There is certainly a lot to do in and within driving distance of Rotarua, so it could be a possibility.
There are way too many options for the South Island for me to suggest anything without knowing more about what you are looking for. But even so, I might suggest two one-week stays, if you definitely don’t want to travel around.
Yep it's pretty hard to to answer without more info from you.
Rotorua is pretty central and has a stack of things to see and do. It can be a bit of a money mucher though. Have you been there before?
An alternative might be somewhere up North. I really enjoyed Paihia and the Bay of Islands. Plenty to keep you engaged for a week.
Queenstown is probably a logical base on the South Island. It's pretty central, easy enough to access Fiordland, the Mt Cook region and also the West Coast Glacier villages and has plenty to see and do itself. It is Tourist Central and also a bit of a money muncher.
We spent two weeks just on the North Island. I don't recommend staying six days at one place. Rotorua was nice and we did spend 2-3 days in that area.
We loved Wellington.
