A family is in mourning after a young father drowned at a beach on Auckland’s North Shore.

Friends and family have paid tribute to the man , who is survived by his widow and recently newborn son.

The 24-year-old was among a group at Rothesay Bay who got into trouble shortly after 5pm on Saturday.

Emergency services were called to a “water-related incident”.

His family and friends said he was devoted to his family.

He had married his partner late last year and the couple had recently welcomed a son.

Photos of the young family show the couple proudly holding up their baby boy, smiling and cuddling him close.

“Rest in peace bro.”

Rothesay Bay residents laid flower tributes overlooking the beach on Sunday.

One of those laying flowers said she didn’t know the dead man or the other individuals involved, but felt she “had to do something” in his memory.

“I see some people have done the same thing, which shows how close the community is.

She said Rothesay Bay is widely known for being fairly quiet and calm, so she wasn’t sure how the individuals got into trouble.

“When you hear about things like this, it’s just awful,” she said.

Nearby residents shared the same confusion at how the group came to grief on the tranquil beach, saying it was a shock to the community.
