In that time England have played 25, won 4, drawn 1; Ireland have played 17, won 3 and drawn 1; and Scotland have played 13 and won 3.
Wales have won three Six Nations crowns and been to a World Cup semifinal with Gatland but cannot wrestle satisfaction from their duels with the Big Three south of the equator.
Gatland's time with Wales began with a flourish in 2008 as they travelled to Twickenham and beat England and went on to win the Grand Slam. They could not beat the Springboks away or at home but nailed the Wallabies 21-18 late that year.
That remains their solitary success with Gatland against the Big Three and an equally rare memory for men like Jamie Roberts and Alun Wyn Jones who were involved that late November day.
This week the All Blacks are in Cardiff for the 14th and final international of their season.
They've had a mixed year with plenty of sublime rugby which spooks any other side and periods of unconvincing work where they struggle to deal with some of the rudiments of the game.
There were several solitary point victories against England, a draw with the Wallabies and a loss to the Springboks which created uncertain frowns mixed with exhilarating displays against the Wallabies in Auckland and Argentina in La Plata.
In several games the All Blacks' mental resilience helped get them home. They will need that again this week even though Wales have made an erratic start to their November campaign.
If there is one game, one match, one test Wales want to win more than any, it is this contest; for so many reasons and so many generations who follow rugby in the principality.
This test will be the main focus in their pre-Christmas programme where all sorts of mixed results will be forgotten if they can find their way to the victory podium.
A win will be an enormous fillip as they work through to the World Cup. Victory would allow Gatland, his staff and the players to shed the crushing hold the All Blacks bring.
Will it happen? The answers are in the unlikely to implausible range of probability. Wales have enough skilled individuals but it's whether they can bring a collective heat to unsettle the All Blacks and keep ticking over the scoreboard.
Even then they'd need to keep their nerve. Ireland last season and Scotland last weekend eyed fame and tripped over their uncertainty. Odds are Wales won't get that close.
