"I am grateful that Her Majesty is taking the time to meet with me in what is an incredibly busy week for her as Head of the Commonwealth," Ms Ardern says.
"This will be my first meeting with Her Majesty so I'm very much looking forward to sharing this Government's vision for New Zealand and our priorities."
The audience is offered to new prime ministers from countries where the Queen is head of state.
"I'll also be meeting The Prince of Wales and The Duchess of Cornwall the previous day at Clarence House," Ms Ardern says.
"Their Royal Highnesses have had two very successful visits to New Zealand over the last few years, so this is a good chance to update them on issues of interest."
Ms Ardern might also get a chance to catch-up with Canada's Prime Minister Justin Trudeau, who has also been invited to the Youth Town Hall meeting at London's City Hall.
"I will be meeting students from three London schools and hearing about the key social issues which concern them like gender equality," says Ms Ardern.
The Prime Minister departs for Europe on Friday 13 April. She will meet the President of France Emmanuel Macron in Paris, German Chancellor Angela Merkel in Berlin and British Prime Minister Theresa May.
