Foreign Affairs Minister Murray McCully has met with the UK's Boris Johnson in London as both countries pledged to do more to increase aviation security.
Mr Johnson hosted Murray McCully as the Foreign Secretary talked up the prospects of a post-Brexit free trade deal with New Zealand.
Mr Johnson has in the past expressed support for closer ties with New Zealand, suggesting ideas like free mobility within the Commonwealth; but since the Brexit vote and his new role as Foreign Secretary, new trade agreements have become his priority.
Mr Johnson and Mr McCully discussed collaboration at the UN Security Council in August to push for greater air safety.
"The UK and New Zealand are not only long-standing friends but we are like-minded global partners across the full range of challenges facing the world today," Mr Johnson said.
"With New Zealand on the UN Security Council, we are working even more closely to promote global peace and stability. As partners in the Commonwealth, we share values, history, language and systems of law and order.
"We discussed the dynamic trading relationship between our two countries and I emphasised that the UK remains firmly open for business. We are the same outward-looking, globally-minded, big-thinking country we always have been.
"The government strongly welcomed New Zealand's enthusiasm following the EU referendum for a free trade agreement with the UK in the future. The UK will want the strongest possible economic and people-to-people links with a close friend and important partner like New Zealand in years to come."
Mr Johnson also praised New Zealand's troop deployments to Afghanistan which he said highlighted the need for ongoing international support for the government in Kabul.
It's turning into one of the worst kept secrets, but the Government's refusing to reveal who's in-line for the next High Commissioner job in London.
UK correspondent Tova O'Brien says the timing of Sir Jerry Mateparae's ending his role as Governor-General in New Zealand is fuelling speculation he's the man for the job.
Murray McCully says at this stage nobody is being ruled out of the candidate pool.
