The recent World Cup's top run scorer blasted 29 fours and 11 sixes in a destructive 227 as he and Shiv Thakor (83) scored quickly to help establish a 236-run lead.
Openers Ben Slater (56) and Billy Godleman (44) set the platform before Liam Norwell (2-107) removed them both.
The visitors continued to accelerate in the final session to end on 511-8.
Guptill and Thakor added 190 runs at a run rate of 6.26 an over to take Derbyshire from 191-4 to 381-5
Gloucestershire were guilty of dropping catches with Slater reprieved from the first ball of the day, before Guptill offered a straightforward chance to Geraint Jones at slip when on 57 and Will Tavare at point on 101.
The Black Cap punished the home side's profligacy, reaching a career-best first-class innings, with three consecutive sixes off Norwell.
The 28-year-old was eventually caught off the bowling of Matt Taylor (5-89), but his efforts helped Derbyshire pile up 487 runs in the day, with youngster Harvey Hosein weighing in with an unbeaten 43 before the close.
