Prevention Sergeant Tim Coudret said police had received calls and social media reports over several days regarding people seeking charity donations on private property.
Police identified and spoke with the collectors to confirm their activities were genuine and gave advice about approaching householders professionally and ensuring identification was visible.
"Always ask for identification and check if you’re unsure," Sgt Coudret said.
"Collectors should also always have a pamphlet they can leave you alone with so you can think about donating later."
He thanked callers for their good instincts and information.
Police are again warning rural residents following a recent increase in remote rural thefts and burglaries, particularly involving diesel fuel.
"With fuel prices rising, offenders have been targeting rural properties at night."
Sgt Coudret said incidents were scattered across the district and urged farmers and rural property owners to thoroughly lock gates and sheds, ensure security lighting was operating and check CCTV cameras were clean and functioning.
A strong focus on impaired driving would continue as winter progressed.
Sgt Coudret advised motorists to expect more alcohol checkpoints throughout Clutha, including more remote areas in coming months.
Roadside drug testing was also being rolled out, with police expected to increase both checkpoint operations and testing with routine traffic stops.
"If you are stopped by police, expect to be alcohol tested and also expect to have a drug test done as well."
Other seasonal reminders included checking vehicle tyres, lights and windscreen wipers before travelling, particularly during colder and darker conditions.
"We’ve seen a surprising number of incidents and serious near misses involving sunstrike. Trusting to luck while you drive semi-blind is not an option . . . Give your windscreen a good clean inside and out now."
Heightened firearms activity throughout deer and duck seasons has heralded an increase in people entering forestry blocks and other land to hunt without permission.
Sgt Coudret said hunters should ensure they had authority to be on any property they entered, follow all firearms storage and safety requirements diligently and be aware seizure and possible permanent confiscation of valuable firearms was common procedure in firearms and criminal offending, along with firearms licence loss.
