International media - including BBC, Financial Times and CNN's Richard Quest have also sought out English for a more in-depth interview.
Asked what his interest in English was, Quest said it was because of the position New Zealand had found itself in following the collapse of the Trans Pacific Partnership courtesy of the election of Donald Trump and Brexit.
He said the United Kingdom was looking for "quick, easy wins" once Brexit happened - and that was behind British Prime Minister's eagerness to sign up early for trade talks with New Zealand.
It could learn a lot from New Zealand about trade negotiations - which the UK has not had to do for itself while part of the European Union.
"How does New Zealand do it? Remember, the UK has not negotiated its own trade deal for the best part of four decades. They don't know how to do it."
"New Zealand is not only an example of a small country that is surviving internationally on its own, but also is going to be one of those touchstones that the UK is going to try to get a very quick trade deal with.
I think what [New Zealand] is is an example par excellence of how a small country, which is resource rich, has great ingenuity, geographically remote but manages to not only survive but thrive in challenging circumstances."
In his piece, the Financial Times' Brussels' bureau chief Alex Barker wrote up the interview as an outsider's view of Brexit, saying English was in Europe to remind them that what happens in Europe washes up on the shores, even in New Zealand.
Securing May's promise of early trade talks was the second victory for English, after European Commission president Jean-Claude Juncker estimated the long awaited trade agreement with the EU could be done in two or three years - an optimistic target but one English would be happy was stated publicly.
