The first couples of New Zealand and Australia will get to know each other better tonight over dinner in Sydney.
Jacinda Ardern and partner Clarke Gayford will have dinner with Malcolm Turnbull and wife, Lucy, at their harbourside home at Point Piper in Sydney.
The trip will be Ardern's first formal visit to Australia since becoming Prime Minister in October. She made a brief trip to Sydney last year to uphold the tradition of all new prime ministers visiting Australia at the first opportunity.
Ardern's departure on an Air Force Boeing from New Zealand was delayed for an hour from the original schedule so she and other senior Cabinet ministers could attend the farewell speech in Parliament of former Prime Minister Bill English.
She is taking a delegation of seven ministers including Finance Minister Grant Robertson, Trade Minister David Parker, Science Minister Megan Woods, Agriculture Minister Damien O'Connor, Commerce Minister Kris Faafoi, Small Business Minister Stuart Nash, and Customs Minister Meka Whaitiri.
