I would recommend:

Exchanging your foreign currency to New Zealand currency (if you could not in the previous destination)

There are multiple foreign exchange facilities at airports, dedicated foreign exchange places, and banks.

There are also ATMs widely available, especially inside supermarkets and malls.

Getting a bus card

Depending on which city you arrive in, having a bus card is great for using cheap public bus transport and is cheaper than using cash to pay for a bus fare.

Getting a local SIM card

Having a sim card with mobile data available can be life-saving, especially if you are visiting rural areas or hiking in the New Zealand wilderness. You will need ID as part of the registration process.

You can top using online using a credit card, or via app, customer service phone call, or in-store.

Main mobile service carriers include:

• 2degrees
• Spark
• Vodafone
