In a rare, one-on-one interview, Prince Harry said he'd "love" to have kids and a wife to "share the pressure" of his royal duties, but he's in no rush to get married.

"I don't think you can force these things. It'll happen when it's going to happen," Harry told Sky News at the tail end of a tour in New Zealand on Sunday. "It would be great to have someone else next to me to share the pressure, but the time will come."

He added that he is thrilled by the birth of Princess Charlotte, his first niece and the daughter of his brother, Prince William.

However, the prince stopped short of predicting when he will have children of his own.

"I would love to have kids right now, but there's a process that one has to go through," he said.

The 30-year-old Prince Harry said he is at a "crossroads" in his life. He is preparing to leave the British military in June after 10 years of service, with the intention of focusing more on his role as a royal ambassador.

Harry said his military career is nearing the point when most officers become captains, before moving on to desk jobs or command posts. The prince said he's not comfortable moving on to a command role while juggling his duties as a member of the royal family.

"I don't really feel as though I would be in the right position to take on the careers of more soldiers," he said. "With all that comes responsibilities and a lot of your time."

Harry added that he wouldn't want to have to get other commanders to "cover" for him at times when he'd be called away for royal duties.

In the interview, Harry dismissed his "party prince" label and stressed that he wants to have a wage-earning pursuit to keep him grounded in between royal tours.

"We feel as though we have to have a wage," he said.

Harry's brother, William, served in the military for almost eight years before leaving the service to focus on his royal duties. Prince William took a full-time position as a civilian air ambulance pilot last year.
