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.
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.
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.

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.
C24 timber is a grade of structural softwood lumber commonly used in construction. It is characterized by its strength and stiffness, making it suitable for various applications, including beams, joists, and framework. The grading system assesses the wood based on its visual and mechanical properties, ensuring it meets specific standards for load-bearing capabilities. C24 timber is typically sourced from species such as spruce, pine, or fir.
Tanalised timber is wood that has been treated with a preservative solution, often involving copper-based compounds, to enhance its resistance to rot, decay, and insect damage. This process, known as tanalisation, helps extend the lifespan of the timber, making it suitable for outdoor use in structures like fences, decks, and garden furniture. The treatment typically gives the wood a greenish hue, indicating its preservative content. Tanalised timber is popular in construction and landscaping due to its durability and cost-effectiveness.
Blackbutt timber primarily grows in the eastern regions of Australia, particularly in New South Wales and Queensland. It is derived from the Eucalyptus pilularis tree, which thrives in coastal and sub-coastal areas, often in well-drained soils. This hardwood is valued for its durability and strength, making it suitable for various construction and flooring applications.
