OPINION: While Boris showered Brits with Budget lollies today, he served up Kiwis a bitter pill. 

His government has increased the National Health Service surcharge for a third time in just four years, which migrants must pay in order to live in Britain. 

An extra £224 (NZ$460) has been added per year for all visa categories, apart from the Youth Mobility Scheme T5 visa, which increased by £170 (NZ$350). 

It means Kiwis under the age of 30 who plan to move to Britain for two years must now pay £940 (NZ$1930), instead of £600 (NZ$1230). 

All other New Zealanders on various visas (like ancestry visas) will have to pay £3120 (NZ$6395) for a 5-year stint, up from £2000 (NZ$4100). 

Just six years ago, Kiwis didn't have to pay anything. And even when the health surcharge was introduced in 2015, we were exempt. 

But in 2016, that exemption was scrapped and the surcharge was £200/year. In 2018 it jumped to £400/year. Now it's £624/year. 

Don't get me wrong, I haven't become a whinging Pom. I'm all for the fair payment of services like the NHS. 

But this latest jump is taking the Mickey big-time.

Not only is it exorbitant and using Kiwis as a cash cow, it charges New Zealanders twice - a decent whack of their earnings is paid as tax in the UK (and at a higher rate than in NZ for most). 

• Proposals for CANZUK
• Post-Brexit Push Afoot to Create New Alliance Between Canada, UK, Australia, New Zealand
• New Zealand happy to forget the UK's 'betrayal'
• Canzuk Defense opportunities in 2019

And, this makes me even wilder: Brits who move to New Zealand don't have to pay a surcharge to use the public health system there. 

The unfairness doesn't stop there; there are more than 250,000 Brits living in New Zealand (more than 5 percent of NZ population), while there's around 60,000 Kiwis living in the UK (less than 0.1 percent of UK population). 

So while a quarter of a million British citizens don't have to pay a surcharge to use New Zealand's system, the 60,000 Kiwis in the UK will pay millions of dollars in surcharge, and again in tax. 

The increase makes the UK OE even more inaccessible to Kiwis, who already have to pay a visa processing fee of NZ$1174, have at least £1890 (NZ$3860) in your bank account, buy a flight (one-way cheapest is around NZ$680), and have cash left over for rent, bond, etc. 

So Boris, why are you continually punishing New Zealanders who want to make a home in your country, contribute to your economy, and importantly, fill jobs you desperately need in health, education, construction, etc? 

It's time the UK ends its disregard for New Zealanders. The extortion must stop. Kiwis aren't leeching off your country, we are contributing to it and adding value. 

Show us all some respect.
