Also If you leave new zealand before your visa expires the visa will be paused until you return, so if you leave after 6 months you can return later and use the remainding 6 months.
Check out immigration.govt.nz for more info and to apply......this is what they say about working holiday visas for british passport holders..........
This bit about the working holiday visa "being paused" is incorrect. It says on this page of the immigration website "any time you spend out of New Zealand will not be added to the time your work permit is valid for".
No. It is not incorrrect. In fact you just proved that with that quoted statement, it reads.........
Q: What if I want to leave New Zealand for a short period of time and return?
A: Your multiple entry work visa will allow you to enter and leave New Zealand freely during the period of your initial work permit.
Any time you spend out of New Zealand will NOT be added to the time your work permit is valid for.
In other words, your permit will freeze and any time out of the country will NOT be added to the time that your work permit is valid for.
Your visa is valid for a year starting from the date that you entered the country. Time spent out of the country isn't "added" to that year, so it remains a year from the date that you entered the country. E.g. if you spend six months inside the country, and then six months outside of the country, the visa is no longer valid. (Rather than having six months of validity left.)
