New Zealand PM has plans for wedding but no set date

New Zealand's Prime Minister could soon be walking up the aisle.

Jacinda Ardern told reporters on Wednesday plans were in place for her wedding, but a date is yet to be set.

The 40 year old leader is engaged to television host Clarke Gayford, 44, and they have a two year old daughter.

She's only the second elected leader to ever give birth while in office, after Pakistian's Benazir Bhutto.

Speaking to reporters, Ardern was coy about the details of her upcoming marriage:

"Yes I can tell you that we have some plans, they are some way, they are some way off. We might need to share some of our plans with our family and friends before we do that more widely."

Last month, Ardern led her Labour Party to its best election victory in five decades, cementing her second term in office.

She's most recently won plaudits for appointing the most diverse cabinet in New Zealand's history.
