Of New Zealand's three regular first choice seam bowlers, Wagner, 32, has been demonstrably the most successful in recent seasons.
In 34 tests overall he's taken 144 wickets at 27.87, but since the Indian visit of early 2014, his numbers have steadily improved to the point where his average (24.4) is significantly better than his two fast-medium teammates Trent Boult and Tim Southee (31.25 and 31.4 respectively).
In that period, remarkably Wagner has been left out of 13 tests, including five in a block of six in the West Indies and the United Arab Emirates.
For what it's worth, Wagner is ranked sixth on the International Cricket Council test bowling chart; Boult is 12th and Southee 17th.
Ahead of Wagner are top class operators — Kagiso Rabada (South Africa), Jimmy Anderson (England), India's spinners Ravi Ashwin and Ravi Jadeja and Australian seamer Josh Hazlewood.
That means there's a pile of quality sitting beneath the bustling left armer. Wagner's not that fussed about it.
''I don't really look at it at all. If you do the right things and do what's required they take care of themselves.
''I try to contribute what is needed for the team to win test matches. That's the most important thing to me. There's far more skilful bowlers on that list.
''It just shows it's a bit of a fickle list so I don't read too much into that.''
As for his steadily improving record, Wagner puts it down to consistency, and absorbing lessons.
''Sometimes you are going to have periods when it doesn't happen for you.
''It's like golf. You don't always rock up to the tee and have a perfect swing. Sometimes it feels a perfect swing and you can't hit the ball straight.
''I try to sum up the conditions early to try and go to whatever plan I'm going to work with Kane (captain Williamson). I try to control the controllables, and be able to execute.
''That's where I have improved a little, eliminate bowling the bad ball, adapt to a role and execute it.''
His only pink ball experience was a two-day warmup game in Perth in late 2015, before the inaugural day-night test at Adelaide, for which he was omitted.
Wagner is in Mount Maunganui with the bulk of the rest of the first test squad until Sunday. He'll be making the most of it.
''It just comes down to mental preparation, staying fresh in your plans and methods.
''We've played enough cricket to know that you hit the ground running and find your feet early. It's no different to playing around the world in different conditions.
''We knew about this (pink ball test) for ages so you make sure you get yourself ready to be the best you can.''
