I've not heard of any NZ timbers that are not food safe.
Timber is found in forests all around the world. It is harvested from trees that are suitable for commercial use, such as pine, oak, mahogany, and cedar. Timber is used in various industries, including construction, furniture making, and paper production.
PBS timber refers to timber that has been treated with a Prolonged Biological Stability (PBS) process, enhancing its durability and resistance to decay and insects. This treatment extends the lifespan of timber, making it suitable for various outdoor applications, such as decking and structural components. PBS timber is often chosen for its environmental benefits, as it reduces the need for chemical preservatives and promotes sustainable forestry practices.
Treated grade C16 refers to a classification of timber that has been pressure-treated for durability and is suitable for structural applications. C16 indicates that the timber has a specific strength rating, making it suitable for use in building projects like floor joists, wall studs, and roof trusses. The treatment process helps protect the wood from decay, insects, and other environmental factors, enhancing its longevity in construction.
While seasoning, timber can warp, making it unuseful.
Timber is not classified as a mineral resource; it is considered a renewable biological resource derived from trees. It is valued for its versatility, strength, and aesthetic qualities, making it suitable for construction, furniture, and various industrial applications. Sustainable forestry practices help ensure that timber can be harvested responsibly while maintaining ecological balance. In this context, timber contributes to both economic and environmental sustainability.
In the construction industry, several types of timber are commonly used, including softwoods like pine, spruce, and fir, which are favored for their availability and cost-effectiveness. Hardwoods such as oak, maple, and cherry are valued for their strength, durability, and aesthetic appeal, often used in furniture and flooring. Engineered wood products, like plywood and laminated veneer lumber (LVL), offer enhanced strength and stability, making them suitable for structural applications. Each type of timber has distinct properties, making them suitable for various construction needs.
In Mexico, timber is primarily used for construction, furniture-making, and crafting traditional handicrafts. The country has a rich diversity of wood species, making it suitable for both structural applications and decorative items. Additionally, timber is also utilized in the production of paper and pulp, as well as in the manufacture of various wood-based products. Sustainable forestry practices are increasingly being promoted to protect Mexico's valuable forest resources.
F72 refers to a specific stress grade for structural timber, indicating its strength and load-bearing capacity. The "F" stands for "Framing" or "Structural," while "72" denotes the timber's characteristic bending strength, measured in megapascals (MPa). In this case, F72 timber can withstand a bending stress of 72 MPa, making it suitable for various construction applications where strength is a critical factor.
J2 timber class is a classification used in Australia to denote a specific grade of structural timber that has been treated to be durable and resistant to decay and insect attack. This class is typically used for various structural applications, including framing and decking, where moderate to high strength and durability are required. J2 timber is often sourced from species that are known for their strength properties, making it suitable for construction in different environments.

You can certainly have a crack at making a boomerang. There are several types, so research it beforehand. Just choose a suitable piece of timber with an angled branch. Lots of fun!
you make timber by planting a tree letting it grow then chopping it down then making it sizes then building a house.
