New Zealanders are being urged to make sure they're up to date with their measles jabs.

As school holidays get underway, travellers are being reminded of outbreaks in Australia, the US, Canada, the UK and Vietnam.

There are no cases in New Zealand currently.

Health NZ’s acting national public health service clinical director protection, Dr Matthew Reid, says there's a risk of measles spreading quickly through New Zealand if Kiwis bring it back home.

"Because our vaccination coverage is not as good as it should be, measles could then spread quite easily."
