The family of the teenage cyclist who was killed after a driver fled the scene of the crash in Auckland have described him as a "loving big brother".
Fifteen-year-old Nathan Kraatskow was killed in the collision.
Emergency Services were called to the northbound Oteha Valley Rd off-ramp shortly before 11pm on Friday.
In a statement Mr Kraatskow's family say it is "an extremely difficult time for our family".
"There are no words to describe how much Nathan will be missed," they said.
"Nathan was a sporty and caring and loving big brother to three younger siblings.
"He will leave a huge hole in our family and we know he will watch over us as our guardian angel. He was also a great, loyal friend to many."
Nathan was a Year 11 student at Vanguard Military School, and had previously spent two years at North Shore high school Rangitoto College.
Police have extended their deepest sympathies to Mr Kraatskow's family.
