But the left-hander was dropped after three matches, and was not given another opportunity at Test level until earlier this year.
Alam scored 30 first-class centuries in the 4188 days between his two Test tons.
As revealed by cricket statistician Andrew Samson, it was the third-longest drought between centuries in Test history.
MOST DAYS BETWEEN TEST CENTURIES
5093 — Warren Bardsley (AUS), 1912-1926
4544 — Syed Mushtaq Ali (IND), 1936-1949
4188 — Fawad Alam (PAK), 2009-2020
Since making his first-class debut in 2003, Alam has compiled 12,724 runs in the game's longest format.
Alam made headlines during the Test series against England in August for his unorthodox batting stance.
As the bowler runs in, Alam faces his opponent front on before adjusting into a more traditional stance at the last second.
It is undeniably bizarre, yet the Black Caps were unable to penetrate his defence for 269 deliveries.
Alam was eventually removed by New Zealand paceman Neil Wagner for 102, gloving a short ball through to the wicketkeeper.
