Most complaints since 2011 were over failed rent payments, followed by property damage and breaching tenancy agreements.
From the 1511 complaints received throughout Northland last year, 480 went to mediation, 686 ended up with the tribunal, 168 were withdrawn and 177 were unresolved.
Rental property manager Sandra Robinson of Mid North Real Estate said a high number of beneficiaries with wrong priorities have exacerbated the problem with rent arrears.
"If the Government can redirect rent to the agents, half the problem could be eliminated because if people are not paying their rents, they're also struggling with their power and water bills," she said.
Last year, 661 complaints to the tribunal related to termination of rental agreement because of unpaid rent.
This was followed by rental areas after tenants have moved out and 116 for termination breaches where tenants have been asked to leave for unpaid rent.
LJ Hooker Whangarei chief executive Paul Beazley said in most disputes between landlords and tenants, efforts were made for an agreement to be reached that both parties could live with. He said an economic downturn, extra rental properties and the fact that landlords and tenants were more aware of their rights could contribute to unpaid rents and a high number of complaints to the tribunal.
Latest census figures show the number of occupied or rented homes and units in Northland increased from 55,932 in 2006 to 60,192 last year.
Several readers took to the Advocate Facebook page to highlight problems they've had with their tenants.
Kaikohe school teacher Brent Samuel Strathdee said his mother had a string of bad tenants, most of who simply wouldn't pay rent. "And one even decided they'd take some of the chattels like curtains and even a fixed bathroom cabinet when they left."
Meanwhile, Jarna Cherry pointed out that renters also struggled with bad landlords, saying she had been ripped off by landlords and property managers and has taken a landlord to the Tribunal.
The tribunal is a specialist court that can award compensation or order repairs up to a value of $50,000. Serious cases of substantial damage, threats and assault, or failing to pay rent for more than three weeks can see tenants evicted.
