All Blacks indiscipline has more than doubled since Steve Hansen took over as New Zealand's coach.
During the 2011 Rugby World Cup cycle, under coach Graham Henry, the All Blacks were carded by a referee once every 338.5 minutes.
That is one in every four and a bit games.
For the 2015 Rugby World Cup cycle, the number of cards doubled.
All Blacks were sent from the field every 166 minutes, or every two games and since then, it is increased to every 139 minutes.
As such, New Zealand have gone from one of the cleaner sides in World Rugby to one of the worst for discipline, particularly among tier one nations.
Over the past four years, the All Blacks have earned more cards than any other tier one side, 31 in just 54 games.
The next spot is taken by Australia, with 30 cards in 55 matches, while Argentina are one card back on 29.
Compare that with Ireland, who have been carded 11 times in 47 matches to be by far the cleanest side in World Rugby since 2013.
South Africa are the second cleanest with just 16 cards in 48 games while Wales and England are close behind.
New Zealand Rugby has been approached for comment on the number of cards the All Blacks have been collecting.
New Zealand's worst offender on the card front is Kieran Read, with five yellow cards since 2008. Sam Whitelock has four since 2010.
Sonny Bill Williams gets a special mention, earning New Zealand's only red card during that period while also receiving two yellows. That comes in just 45 games.
