Publication date

Timber slat decks are supported by joists, bearers and piles and have gaps between the decking timbers so rainwater can drain away. A deck less than 1.5 m above the ground does not need a building consent but must comply with the New Zealand Building Code and may require a resource consent. A barrier is required if it is possible to fall more than 1 m from the deck.
