At the outset of the New Zealand-UK free trade agreement, the British Government made the point of highlighting that New Zealand and the United Kingdom “share” a head of state. Yet as we get down to the details of the agreement, there are some glaring omissions. Radio New Zealand reports that while the British Government is championing the deal removing tariffs on some goods, others - goods that New Zealand exports to the UK - appear to be missing:

New Zealand International Business forum executive director Stephen Jacobi said the glaring omission was no mistake.
"Beef, lamb and dairy are the three most sensitive parts of the negotiation, it's great the UK government is preparing their public for an ambitious outcome but the outcome has to speak to our major items of trade interest other wise there's not point in doing a deal," Jacobi said.
"I fully encourage our government to be as far leaning as they possibly can on those areas to clinch this deal. It would be absolutely ridiculous if we were to enter into an FTA with the UK that did not put forward the prospect of free trade, zero tariffs in lamb and beef and dairy within a reasonable timeframe."
UK farmers have raised concerns that a free trade deal could undercut them.

Once again, it’s clear that a “shared” head of state does nothing for us. The very idea that it could is laughable. Instead, we have the reality of international trade and agreements between countries generally; everyone has their own national interests.
