But, even when factoring in a track which offered little for any bowler, he would have rightly expected more out of his spin-bowling duo, especially considering the hosts' slow-bowling troupe claimed 16 of the 17 tourists to fall.
Despite Shere Bangla National Stadium historically offering something for the spinners, it would be no surprise if the selectors play an extra paceman in the second test.
Bruce Martin and Ish Sodhi did little in Chittagong to warrant retention and, with Neil Wagner and Mark Gillespie waiting in the wings, one of the pair could make way, especially after Kane Williamson demonstrated his proficiency with the ball.
Sodhi did finish the match with three wickets and the 20-year-old will only benefit from further exposure. Martin, though, seems likely to strike only if a batsman plays a poor shot, and he should consider himself fortunate if his brace late on day five sees him survive.
Corey Anderson will be the other man watching over his shoulder in the nets this week. New Zealand have in recent season struggled to find an all-rounder who adds value in both facets of the game, but the test debutant was twice dismissed cheaply to go with his two wickets.
The inclusion of an extra seamer could see Anderson replaced by Dean Brownlie in the middle order, though that would leave New Zealand with just five genuine bowling options.
Bangladesh needed only one to rip through New Zealand's middle order on the final day, with Gazi victimising the tourists on the same surface their own slow bowling unit found so lifeless.
The off-spinner had already claimed a couple of wickets in the first innings when he produced a moment of magic in his second turn with the ball. After picking up Peter Fulton (59) and Kane Williamson (74) in the morning session, Gazi trapped Anderson in front before inducing edges from BJ Watling and Doug Bracewell to send both back to the pavilion first ball.
It was the first test hat-trick against New Zealand since Ryan Sidebottom in 2008, while Gazi - following his unbeaten 101 batting at No 8 - became the only man in test history to score a century and snare scalps on three consecutive balls in the same match.
