Otago Fish & Game officer Ben Sowry said the two offences recorded were one instance of fishing without a licence, and another involving an angler trolling with two rods.
Mr Sowry said they were the most common infringements of the rules.
Fishing without a licence was a criminal offence and people could be liable for a fine of up to $5000 and forfeiture of their fishing gear.
The fine was less for those who trolled with two rods, he said.
"If you've caught a fish illegally, it's not yours. So you don’t get to keep it.
"But it still leaves a bit of a nasty taste, even though you don't get to eat it."
Despite the two offences, Fish & Game applauded the "exceptional compliance" with the fishing regulations from anglers across the region.
He said officers actively patrolled popular fishing spots on lakes and rivers across the Otago region, and more than 200 anglers were checked during the holiday season.
"It’s great to see the compliance so good.
"In a usual year, it would be common to pick up a couple of offences every day, but this year people have been behaving."
Mr Sowry said weather conditions were less than ideal, with plenty of wind and rain discouraging anglers, but the cooler weather had its advantages.
"Catches have been pretty good with the slightly cooler weather helping to keep the trout and salmon feeding in shallower water.
"The weather over the holiday period in the lakes area hasn’t been the classic Kiwi summer, but those who did get out on the water have not only followed the rules, but also enjoyed some rewarding fishing."
Mr Sowry said fishing licences were more than a legal requirement. They unlocked "a world of exceptional fishing" across Otago.
"By purchasing a licence and following the regulations, anglers are directly supporting efforts to conserve and restore local fish habitats, ensuring sustainable populations for future generations of anglers."
He reminded anglers to review the fishing regulations at the start of each season to stay informed about any changes, and refresh their knowledge of the rules.
