The table below summarises the plug types, voltage and frequency of electrical current in both Papua New Guinea and New Zealand.
| Papua New Guinea | New Zealand | |
|---|---|---|
| Plug Types | I | I |
| Voltage | 240V | 230V |
| Frequency of electrical current | 50Hz | 50Hz |
Papua New Guinea uses Plug Type I.
No adaptor needed
New Zealand uses Socket Type I, which is the same as the plug type of your appliances from Papua New Guinea. You will not need an adaptor.
The voltages found in Papua New Guinea (240V) and New Zealand (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Papua New Guinea and New Zealand is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
