They added, “The 35-year-old finishes as New Zealand’s all-time leading international run-scorer with 19,346 runs, including 48 centuries and six double-centuries.”
Williamson debuted for the Kiwis in 2010, and propelled them to an iconic win the first-ever World Test Championship (WTC) 2021 against India.
He even spearheaded them to two consecutive ODI World Cup finals in 2015 and 2019 respectively, but the team finished at the losing end on both occasions.
“I’ve thought about it for a while, but over the last few days it’s become clear now is the right time. I’ve always felt a strong drive and hunger for international cricket, and I take pride in knowing I’ve given it my all in every match I’ve played for New Zealand.
“Continuing with anything less wouldn’t be right and I feel fortunate to step away on my own terms.
“I leave feeling optimistic about where this group is heading. There’s a huge amount of talent, and a real desire to do something special with this New Zealand team,” he added.
In the longest format, Williamson played 110 games, and aggregated 9515 runs at an average of nearly 55. He brought up 33 tons and 38 half-centuries in the red-ball game, whilst registering 15 three-digit scores in ODIs.
For a few years, Williamson had opted out of the rigid NZC contractual system, opting a more flexible route, which allowed him to prioritise his franchise cricket commitments too.
