Olympian and Black Sticks great Simon Child is ending an almost 20-year international career.

Child first stepped onto the international stage in 2005, as a teenager, going on to represent New Zealand more than 300 times.

Renowned globally for his goal-scoring prowess, Child's 148 goals place him as the second-highest scorer in the history of New Zealand men's hockey.

Child said representing New Zealand was his "greatest achievement" and he was "incredibly grateful for the journey".
