"His mum surprised him last week and the rest of his fam came down today … Who's cutting the onions?"
The Frankfurt-born Segner has been playing his first Super Rugby season with the Blues.
The 20-year-old loose forward arrived in New Zealand in what was initially meant to be a six-month exchange at Nelson College in 2017, before going on to become one of New Zealand's hottest young prospects.
Before the start of the season, Segner said he hopes to one day become Germany's first All Black.
"At the moment, I'm pretty settled and happy here in New Zealand," Segner said.
"First and foremost is obviously the Blues, and then hopefully that pathway takes me through to the black jersey, but we'll see how rugby develops over in Germany.
"Hopefully, with what I'm doing over here, can help further the game back home as well. We'll see where things take me, but, at the moment, my focus is on the Blues and, from there, the All Blacks."
