Kiwis travelling to the UK on a youth mobility visa will soon be able to stay there for three years, instead of two.
The deal was reached last year - but has been brought forward to start from July.
The same agreement means young Brits will be able to come here for three years - and the age band has been extended to people up to 35 years old.
Prime Minister Chris Hipkins says bringing forward the extension will help support businesses through labour shortages.
