I don't mean to be a Debbie downer, just want to provide some context into how we currently are and the requirements we currently have for travel. It is so hard to say what will happen as things change rapidly but as we are now I would say NZ will not be open for travel until other countries can demonstrate there is no spread in the community consistently.
Locally thought, most are great and we have very few restrictions. The only thing is to wear a mask on public transport and you are strongly encouraged to keep a diary of your movements for contact tracing if needed. We can travel domestically and have concerts, events, weddings etc, all stores and restaurants are open we can dine in, and most people are very pleased with how the country has handled it.
I hope you can complete your trip here as NZ is a great place to travel!
