Stand in New Zealand one day captain Kane Williamson will have an extra option at the bowling crease for the remaining limited overs matches against Pakistan - himself.
The 24-year-old, who was found in biomechanical tests in July to have been bowling with an illegal action, has been cleared by subsequent tests by human movement specialists at the International Cricket Council-accredited centre at Chennai's Sri Ramachandra University.
The testing on November 23, between the second and third tests against Pakistan in the United Arab Emirates, proved his bowling action was within the permitted 15 degrees of flexion.
In a statement released earlier this week, the ICC said "following remedial work and a re-test, the bowling actions of Sri Lanka's Sachithra Senanayake and New Zealand's Kane Williamson are legal and they can now resume bowling in international cricket."
Senanayake was cleared after being reported for an illegal action during a one-day match against England in June.
The result comes as no surprise considering Williamson was witnessed bowling with a drastically altered action in Mount Maunganui last month during preparations for the national side's tour of the UAE.
Williamson was relieved to have put the five-month process behind him.
"It's a good feeling to be cleared, there's been a lot of work put in to correct the action so it's nice to pass the test," he said.
"It's one of those things that when you have it taken away from you, you want it a bit more and when you have it, you take it for granted a little bit."
The clearance is hugely significant for the Black Caps, who had previously used Williamson's dual talents to gain better balance with both bat and ball.
The decision to play spinners Daniel Vettori, Ish Sodhi and Mark Craig in the third test against Pakistan - though it helped produce an outstanding test win - was likely forced by Williamson's unavailability with the ball.
And while his statistics do not make great reading - he has taken 24 test wickets at an average of 40.66, 23 wickets at 30.91 in 54 ODIs and three T20 wickets at 37 - a failure to have the ban overturned would have had huge ramifications.
An unsuccessful outing would have brought a year-long ban and thrown the planning for next year's 2015 ICC Cricket World Cup on home soil into disarray.
He credited working with coaches for English county side Yorkshire and guidance from New Zealand spin coach Paul Wiseman with helping him make the change.
"It was a good process to go through and I think a good initiative from the ICC. I've enjoyed working on my bowling, it's something I haven't done a lot on in the past, that's probably why my action lost itself a little bit."
He was not sure when he would bowl in a match situation but added it was important for him to grow accustomed to bowling in pressure situations.
