Agathis australis
Agathis australis, commonly known by its Māori name kauri ('kɑːʉɾi), is a coniferous tree in the family Araucariaceae, found north of 38°S in the northern regions of New Zealand's North Island. It is the largest (by volume) but not tallest species of tree in New Zealand, standing up to 50 m tall in the emergent layer above the forest's main canopy. The tree has smooth bark and small narrow leaves. Other common names to distinguish A. australis from other members of Agathis are southern kauri and New Zealand kauri.
Auckland
Auckland (ˈɔːklənd ; Tāmaki Makaurau) is a large metropolitan city in the North Island of New Zealand. The most populous urban area in the country and the fifth largest city in Oceania, Auckland has an urban population of about It is located in the greater Auckland Region—the area governed by Auckland Council—which includes outlying rural areas and the islands of the Hauraki Gulf, and which has a total population of .
Northland Region
The Northland Region (Te Tai Tokerau) is the northernmost of New Zealand's 16 local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The main population centre is the city of Whangārei, and the largest town is Kerikeri. At the 2018 New Zealand census, Northland recorded a population growth spurt of 18.1% since the previous 2013 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty Region (2nd with 15%) and Waikato (3rd with 13.
Copal
Copal is a tree resin, particularly the aromatic resins from the copal tree Protium copal (Burseraceae) used by the cultures of pre-Columbian Mesoamerica as ceremonially burned incense and for other purposes. More generally, copal includes resinous substances in an intermediate stage of polymerization and hardening between "gummier" resins and amber. Copal that is partly mineralized is known as copaline. It is available in different forms; the hard, amber-like yellow copal is a less expensive version, while the milky-white copal is more expensive.
Varnish
Varnish is a clear transparent hard protective coating or film. It is not to be confused with wood stain. It usually has a yellowish shade due to the manufacturing process and materials used, but it may also be pigmented as desired. It is sold commercially in various shades. Varnish is primarily used as a wood finish where, stained or not, the distinctive tones and grains in the wood are intended to be visible. Varnish finishes are naturally glossy, but satin/semi-gloss and flat sheens are available.
Resin
In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins. Plants secrete resins for their protective benefits in response to injury. Resins protect plants from insects and pathogens. Resins confound a wide range of herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as parasitoids or predators of the herbivores that attack the plant.
Amber
Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects. Amber is used in jewelry and has been used as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions.
