Hi Varun. NZ is a lovely country. Ive been there in 2017. You can either go only to North Island (Auckland, Rotorua, Bay of Islands) or only South Island (Christchurch and Queenstown). These 5 places are the most touristy, you can club both the islands too. NZ packages are expensive, majorly due to flights, as the flights alone will cost you around a lac, so try grabbing some good deals/discount on airfare. If you are doing both, North and South then you will have to take an internal domestic flight (you can opt for a ferry also,but it will take time) If you are an explorer, you are free to venture in some unexplored places and activities in NZ. You can opt for Self-drive too (a lot of honeymooners hire a car) provided you have an Indian driving license and a credit card on your name. You can ask me if you need a detailed info about any specific location.
