Auckland Transport issued 12,000 parking fines in the last year in the early hours - that's 33 every night while you were sleeping.
And the night patrol has scooped close to $1 million with tickets issued between midnight and 6am.
Victims who have woken up to $40 fines on their windscreens have slammed the practice.
"It's revenue-gathering. It's really that simple," said Michelle Konik, whose son was ticketed in a 2am blitz in Tautari St, Orakei.
Auckland Transport employs a dedicated night team.
Figures obtained by the Herald on Sunday show 12,028 tickets were issued in greater Auckland between midnight and 6am from August 2014-2015.
The combined fines were worth $914,724 to council coffers.
The figures also show the council-controlled organisation has budgeted revenue of $31.9m this financial year from parking fines.
That revenue target equates to a basic $40 parking fine being issued 797,500 times - or 2184 tickets a day.
