WELLINGTON, Jan. 17 (Xinhua) -- New Zealand Prime Minister Jacinda Ardern will promote free trade agreements with Britain and the European Union and the government's wellbeing agenda to global leaders during her European trip next week.

The primary purpose of the visit to London, Davos, Switzerland, where the World Economic Forum will be held, and Brussels is to progress a free trade agreement with Europe and to promote New Zealand business interests, Ardern said in a statement on Thursday.

In Britain, Ardern is scheduled to meet with her counterpart Theresa May and reconfirm the understanding that New Zealand will be left no worse off, including in respect of its trade interests, following Brexit, the statement said.

"My visit to the UK is an opportunity to underline New Zealand's position as a natural and long-standing partner for the country as it redefines its global role post-Brexit," Ardern said.

In Brussels, the prime minister will have meetings with presidents of the European Council and the European Commission, as well as NATO secretary general, to discuss climate change, social policy, trade and the commitment to the rules-based system, according to the statement.

At the World Economic Forum in Davos, the prime minister will be promoting the government's approach to inclusive growth through the Wellbeing Agenda, and the delivery of the world's first wellbeing budget in May this year, it said.
