I cannot recommend this program enough. The staff at IES are so kind and willing to help with anything and everything you might need. They also have awesome orientation programs set up to help the group bond and get an introduction to the culture. We got to spend two nights on Waiheke Island (just a ferry ride away from Auckland), where we stayed in a Maori marae (meeting house for the native New Zealand peoples).
New Zealand itself is simply wonderful. From the amazingly kind-hearted people to the incredible outdoors, New Zealand offers an experience you will never want to end!
