If you need to call someone or find a business, just call 018. They can help you from their up-to-date listings of all New Zealand phone numbers and addresses. All they need is a name (even if you don't know the exact spelling) and a rough address.
If the number and address are listed, they'll give them to you. If you've called from your Vodafone mobile, they'll even follow-up with all the details in a TXT.
If there's a few matches, they can help you zero in on the right one.
If you want, you can even connect directly to the number by pressing 1 – no need to write anything down.
If you need an international number, call 0172.
To protect people's privacy, there are two situations where 018 can't help you:
018 and 0172 services are managed by The Yellow Pages Group. For more information, or if you have a problem, call Yellow Pages on 0800 803 803. You can also find more information on the 018 website.
