They're royal in their mothers' eyes
The first words most mothers expect to hear after giving birth is whether the child is a boy or girl.
But for new mum Caitlyn Adams it was, "You've beaten all the other Kates".
Adams was one of at least six Christchurch women whose babies were born within hours of Britain's newest heir to the throne.
The Duchess of Cambridge, Kate Middleton, delivered a son, weighing 3.8 kilograms (8lbs 6oz), at 3.24am yesterday, or 4.24pm on July 22 in England.
The happy new parents emerged from the hospital this morning with their newborn son, greeted by cheers from a waiting crowd.
Kate said she felt "very emotional", while her husband appeared relaxed and joked with reporters.
"He's got her looks, thankfully," William said. "He's got a good pair of lungs on him, that's for sure.
"He's a big boy; he's quite heavy."
He laughed when a reporter asked him about the baby's hair.
"He's got way more than me, thank God," he said.
Confirming the baby was overdue, William said: "I will remind him of his tardiness when he is older. We're still working on a name."
In Christchurch, new parents are feeling the same delight.
Adams, 32, gave birth to son Samuel at 8.11pm on July 22, meaning he now shares the royal baby's birthday.
"While I was in labour I got texts saying Kate was in labour too. They told me I had to beat her - and I did," Adams said.
"It's pretty special because of everybody celebrating. It's definitely something to tell him as he grows up."
Fellow mum Emma Graham, 37, gave birth to Henry Graham at 4.29pm on July 22.
"I thought I would be pretty close to Kate when I heard she was due around the same time as me, but it's still a bit of a surprise they have the same birthday,'' she said.
''They will hopefully have different names, though, so won't be too similar."
A few more Christchurch babies were born closer to the time of the British prince, but do not share the same birthday.
Elisa Muao is believed to be the Christchurch woman who gave birth closest to Kate Middleton.
Muao welcomed Cecilia Lisa Sapi-Muao to the world at 2.53am on Tuesday, just half an hour before the new prince's arrival.
"I hadn't thought about it at all. I heard the midwife talking about it when I went into hospital and it was a bit of a surprise," Muao said.
"It's strange to think we are part of history and that I gave birth at almost the exact same time as a member of the royal family."
Cecilia, who weighed 3.25kg, is Muao's fifth child.
Anna Sutton, 37, gave birth to Monty within hours of the royal baby - at 7.30am on July 23.
"It was a bit of a joke that we could give birth at a similar time. My brother rang me last night and told me she was in labour and I should hurry up, but I wasn't due for another 10 days, so I thought I'd missed out," she said.
"Then it was all on and suddenly he was born. It's funny because they won't actually share the same birthday because of the date difference, but he was born nearly at the same time."
Mum Natasha Glausiuss' son, Gus Alexander Glausiuss, was not due until next week, but an early caesarean at Christchurch Women's Hospital saw him born on the same day as his royal peer.
She said she thought she would miss out on the royal connection, but her family in England were excited their newest addition would share the same birthday.
Jessie Turner-Robinson's new daughter also arrived early to share the royal date.
Turner-Robinson's 3.15kg baby has not yet been given a name, but it is unlikely she will take on a royal moniker.
"I don't really follow that stuff," the new mum said. "I found out afterwards; everyone's been reminding me all day."
