Prime Minister Jacinda Ardern will meet the Queen in London next week.

Ardern will meet Her Majesty Queen Elizabeth in a private audience at Buckingham Palace while visiting London for the Commonwealth Heads of Government Meeting.

Ardern said she was grateful the Queen was taking the time to meet with her.

"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," Ardern said.

"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 with the Queen is an "on appointment" audience, which is offered to new prime ministers from those countries where the monarch is head of state.
