Across the Tasman

NZ and 1800 questions
How do I call an NZ 0800 number from Australia?
Generally you cannot — NZ 0800 numbers are domestic to New Zealand and not published for international dialling. Use the business's website or a geographic NZ number dialled as +64.
Can NZ callers dial an Australian 1800 number?
Generally no — Australian 1800 numbers are domestic too. NZ callers reach Australian businesses through +61 geographic numbers or online channels.
What is the difference between 1800 and 0800?
The country. Both are national toll-free formats — 1800 in Australia, 0800 in New Zealand — run on separate networks with separate pricing and rules.
My business serves both countries — what do I publish?
An Australian 1800 for callers in Australia and an 0800 from a NZ provider for callers in NZ, each labelled with its country, alongside web and email channels.
Australia and New Zealand each run a national toll-free system, and the prefixes differ: 1800 in Australia, 0800 in New Zealand. The two facts that follow from that are symmetrical — an Australian 1800 will not dial from New Zealand, and an NZ 0800 will not dial from Australia — because toll-free ranges are published for domestic dialling only.
Calling an NZ 0800 from Australia
- Check the business's website for email, forms or chat.
- Look for a geographic NZ number — a landline with an area code (09 Auckland, 04 Wellington, 03 Christchurch).
- Dial it in international format: Australia's exit code 0011, then 64, then the area code without its leading zero, then the number.
- Expect Australian international rates — the NZ free-call arrangement covers NZ callers only.
Calling an Australian 1800 from NZ
Same wall, opposite direction: the 1800 range is domestic to Australia. NZ callers use the business's website, email or a +61 geographic number — the route set out in are 1800 numbers free in New Zealand.
