At the dinner break, with two hours play remaining in the match, New Zealand were 301 for five, with Mitchell Santner on 26 and Luke Ronchi on eight.
Having seen opening partner Tom Latham, out of sorts Hamish Rutherford and captain Brendon McCullum depart for a baseball-themed 49 in 28 balls, Guptill cashed in to make the most of his one pre-test pink ball opportunity.
He had some early troubles against lively seamers Joel Paris and Andrew Tye but drove impressively and often.
Guptill struck 12 fours and four sixes, one of which, over long off, took him to his half century; and another hit straight got him to three figures, whereupon he walked off. His 184 minutes and 109 balls has given him the best available preparation for what lies ahead.
Rutherford looked uncomfortable, hardly surprising as it is just his third bat in a month, but McCullum was out there for a good time, not a long time.
Mitchell Santner took 16 balls to get off the mark, but did it lofting legspinner Liam O'Connor deep into the Lillee Marsh stand behind the bowler.
BJ Watling hit 81 off 117 balls in a tidy performance, with 12 fours and a six.
Meanwhile former Australian test skipper, and Cricket Australia board member, Mark Taylor has called for the introduction of four-day tests, hot on the heels of the first pink ball test.
''The younger generation generally want more instant gratification and I think over five days to keep them interested in the game is not so easy," Taylor told News Corp last night.
"Why are we surprised when people go to one-day cricket and T20 cricket more than they do a test, when we put all the one-dayers and T20s on in school holidays and at night, and we put test matches on during the week outside of school holidays."
