''Guys want to play more test cricket. The team love playing test cricket.
''Four tests this year (two against the West Indies two against England), the guys weren't ecstatic with (that). We know the coming (year) has a lot more. We have to be patient.''
Williamson reckons there could be as many as eight tests coming in the next 12 months, possibly 10 the following year.
Remember the last away test for New Zealand was October 2016, which is 12 tests ago, and that is barely believable.
Still Williamson drew a distinction between wanting more and more tests, and focusing on his team's development.
''As a test team we are growing and improving but there's still work to be done.
''The focus isn't so much on crying out for more, as it is about how we want to approach our cricket as a team, day in, day out. I think that is most important,'' he said.
The expectation is that the two incoming touring teams next season will be Sri Lanka and Bangladesh, with one-day activity against Australia and India as well.
There's no great secret that the chief focus will once again be on ODI cricket, ahead of next year's World Cup in England.
So for now, New Zealand should cherish the events in the England series and what it's brought – namely a jump to No 3 on the world test rankings, behind only India and South Africa.
''The guys are pretty stoked,'' Williamson said.
''It was a great way to finish a campaign which had a lot of white ball cricket. But the way the test team performed was superb in a number of different situations.''
He's not one to dwell on what's gone too long, though.
''It's all about moving on to what's coming next,'' he said.
In Williamson's personal case, that's another stint with the Sunrisers Hyderabad, and this time as captain, having replaced disgraced Australian David Warner.
