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