Residential Tenancies Act 1986, ss 62-62B
You should try to arrange for someone to pick up your belongings (“property” or “goods”) during the notice period.
If you can’t arrange for someone to pick up your property within the notice period, or the landlord has agreed to terminate the tenancy immediately, then the landlord can move your property. You should try to come to an agreement about storing your property with your landlord. Otherwise they can throw out anything that would go rotten or that would cost more to store than it would sell for.
No matter what, they must take any of your personal documents to the police.
Even if you don’t have an agreement about storage, the landlord must store any goods that have a value above what the cost of storing it would be. The landlord has to store these goods for at least 35 days. You can claim these back from the landlord by providing a receipt of the goods and documents you want. The landlord is allowed to charge you for costs of moving and storage before returning your belongings. If you don’t claim the goods within 35 days the landlord can sell them.
