Association secretary Ros Morshead said if the reports were true, it was disappointing and a timely reminder for people to be vigilant.
"We are not sure how widespread it is, but these people could be trying to take advantage of a vulnerable and stressed community.
"Remain vigilant and call the police if there are any suspicions."
She said it was definitely not a member of the association.
Rotorua police crime prevention manager Inspector Stu Nightingale said he had not yet been briefed about the Lynmore situation but he issued a general warning.
"If any people have come to your door asking for money that they should not be asking for, just report it to the police.
"Some people will do this before they do a burglary to see if anyone is home.
"Call us about any suspicious behaviour, and unless they are legitimate, ask for ID, or send them packing.
"No one should have any reason to be intimidated by them. But, there are plenty of opportunists out there who will try anything. If you don't feel comfortable, don't speak to them and call the police."
