Yet the British in New Zealand are here because our country welcomed them in as migrants. This is simplistic, of course, and it is a question of degree. In 2015, net migration to the UK was around 333,000 - the second highest level on record.
You could call it racism, you could call it xenophobia, but I suspect even the most moderate and open-minded of Brits can't be blind to the idea that just about everyone who serves you coffee in England is from another country.
We used to joke that Kiwis and Aussies flatted seven to a house in Earl's Court in London, but this is happening in cities like Oxford, and to a far greater extent than the antipodean invasion to the UK.
So, the weight is definitely there, and perhaps it is too much. It is more than just numbers. It becomes a confused, mixed-bag culture in a country which is certainly used to different people and different languages, but it could be argued as unfair on a small nation.
I would like the UK to stay in the EU, but I also think the free movement policy has strained the country enough.
I don't think it is racist to argue that there are limits to what a small country can take.
