Israel Dagg and wife Daisy welcome second child

All Black Israel Dagg and his wife have welcomed their second child!

Daisy Dagg announced the birth of daughter Tilly McKenzie Dagg last night on Instagram, sharing a picture of the newborn.

She captioned the photo: "Daddy’s little princess already."

Daisy - who's already mum to son Arlo with Israel - revealed Tilly weighed 7.5 pounds (3.4kg).

The couple announced her pregnancy at 21 weeks last year. She said the pregnancy was unplanned.

"It was a bloody shock, wasn't exactly planned this early on, was only not pregnant for 4 months and there will be a 13 month gap between them," she wrote on her photo.

"But .... we are super happy and can't wait to meet the next wee addition to our fast growing family."

The couple tied the knot in 2014 at a lodge in the Hawke's Bay. They announced their engagement in 2013.

Congratulations Dagg family!
