Landlords also filed seven complaints over tenants abandoning the premises and two for assault.
Most of the applications resulted in tribunal orders, about a quarter went to mediation, while the rest were withdrawn or unresolved.
Wairarapa property manager Kathleen Clendon said the Tenancy Tribunal was "not helpful at all".
Getting a tenant evicted took a "long time," even when they were paying no rent.
"We might want to get rid of a tenant because they have trashed a property or they are so far behind in rent arrears and they've used every excuse," she said.
"So we've taken them to the tribunal and the tribunal will make us wait six weeks to evict the tenant. In the interim, they stop paying their rent, so more money gets added to the landlord's bill."
Ms Clendon had just taken over a property where the tenants had "done a runner", leaving behind a $20,000 fix-up job.
"They left a fridge full of food, didn't clean up before they left ... the place was a pigsty with drug utensils everywhere." Disposing of the rubbish alone cost $1200, she said. APNZ
