In an email to homeowners, Harcourts said it could not absorb the letting fee because of the extensive work involved in finding new tenants for a landlord.
It said it would charge a new fee to landlords from next month. The charge would be the equivalent of one week's rent plus GST, and would come out of the first rental payment after a tenancy changes.
"It is anticipated that landlords will attempt to recover the cost of the letting fee through increased rent," Harcourts said.
Quinovic Group also confirmed it would charge a "tenancy fee" to landlords, though its charge would be a flat rate of $550 plus GST.
Chief Operating Officer Paul Chapman said the removal of letting fees would have "a considerable adverse impact" on the company and it had forced Quinovic to review its charges.
"Rather than seek to increase our base management fees we have decided to introduce a New Tenancy Fee," he said.
He said finding new tenants was time-consuming and costly, and included credit checks, advertising, viewings, tenant selection and reference checks.
The $550 charge would recover only part of the costs of finding new tenants, he said.
Crockers Property Management said it would introduce an "admin fee" of $20 a month for landlords, which would be charged regardless of whether a tenancy changed or not.
Barfoot and Thompson director Kiri Barfoot said the company had not finalised its plans, but it was likely to introduce a letting fee for landlords, probably set at a week's rent.
"It's a lot of work finding a tenant, and we don't expect our people to work for nothing. So we'll be looking to pass that cost on."
It was up to the landlord whether they passed on that cost, she said.
Barfoot said the ban on letting fees would likely lead to landlords seeking longer, fixed-term tenancies.
"Landlords might be a bit more fussy who they take on. They will say 'If you only want to stay for six months, I'm not going to take that because I have to pay the fee each time'."
NZ Property Investors' Federation executive officer Andrew King said it was reasonable to expect that property managers would need to recoup their costs after the law change.
He noted official advice to the Government that landlords would pass the letting costs on to tenants, and that the likely increase in rent would be $10 a week.
"Given that the average tenancy is around two years, this would mean that tenants actually end up paying more than the original cost of the letting fee," King said.
"A benefit of this is that the cost would be spread out rather than being the current large and up-front letting fee."
