Boys run in the Janssen family, and all four generations got together in Nelson.
They gathered at the family home of great-grandfather Will, who is 87. His son, Will, 59, came up from Timaru, along with his son Kurt, 31, from Christchurch and his son, the newest member of the family, Theo, who is seven weeks old.
Kurt said it was rare to have four generation of males together from the same bloodline, and he didn't know of any other examples.
Mr Janssen senior emigrated to New Zealand in the early sixties and married Dutch-born Irma.
They have turned out to be a sporty family, the great-grandfather a competitive gymnast, his son Will a runner who trained with John Walker and Kurt is a mountainbiker. "It's too early to tell with Theo but he is active," said Kurt.
The family enjoyed Christmas together as well as celebrating Mr Janssen's 87th birthday.
They plan to get together again at Easter.
