From sleepy New Zealand hillsides to sleek Tokyo dining scenes, a bottle of Hawke's Bay wine shipped to Japan traces an arc that exporters like Nigel Avery see as an avenue for multimillion dollar growth built on a free trade pact.

Avery's Sileni Estates hopes to gain as the two countries are among a group of 11 ringing the Pacific Ocean that have carved out a tariff-busting deal, just as the United States and China remain enmeshed in trade disputes and business in Europe is racked by Brexit.

Even without the United States, pulled out of the accord by U.S. President Donald Trump, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) covers an area that houses more than a tenth of the world economy. That opens tantalizing prospects for niche industries like Malaysian rubber, Australian beef and New Zealand's wine trade, now coveting affluent drinkers in Japan.
