Things to do before you fly
Most of the things are done before applying VISA. After VISA you need to buy ticket to fly, that's all.
If you would like to have shopping, you may want to do that as New Zealand is more expensive than Nepal. We recommend you to have moderate shopping than heavy as you may not use them all once you arrive in New Zealand.
Arranging accommodation in New Zealand, arranging someone to come to pick you up from airport in New Zealand are something very beneficial but optional things to do. If you need assistance, please feel free to write to WNSO New Zealand, at: firstname.lastname@example.org.
