New Zealand won the inaugural WTC title by defeating India in the final.
For fast bowler Trent Boult, the WTC triumph is one of the proudest achievements for any Kiwis and he feels the exceptional feat is unlikely to be repeated again.
"For us even to get to that stage as a Test-playing nation of however many people (five million), playing probably only eight Tests a year - if that," Boult, who is currently playing the Big Bash League, told 'The Age'.
"To get two years of results to get into the final, and then beat India - 1.4 billion people - will never happen again. I think that's one of the proudest achievements any New Zealander could have, when you look at the sheer size of it,” he added.
Last year, New Zealand Cricket (NZC) agreed to release Trent Boult from its player contract list, allowing him to spend more time with his family and feature in domestic leagues around the globe.
"I'm incredibly proud of what I've achieved in the Test arena. But I've got three young kids and I look at my career as a length of string. I feel like I'm at the later end of that piece of string."
"I've chosen to go into two other leagues around the busiest time in the New Zealand cricket summer. I do understand that the decision to give back my contract obviously is going to open the door for other people."
Boult is also hoping that his recent decision will not complicate his chances of playing in the ODI World Cup later this year in India.
"I want to be there to have another crack and I hope that is still the case. It's still a wee way away."
According to Trent Boult, opting for the freelance route is okay for cricketers who are in the twilight of their careers but youngsters preferring T20 leagues instead of international cricket is a cause of concern for the BlackCaps.
"It might be common for guys at a certain point of their careers. I think if kids who have played a year of international cricket are choosing to do it over international cricket, that might be a worry.
"There's not a heck of a lot of cricketers in New Zealand. There's not a lot of people!"
