BLACK represents Te Korekore (the realm of potential being). It thus symbolises the long darkness from which the earth emerged, as well as signifying Rangi - the heavens, a male, formless, floating, passive force.
RED represents Te Whei Ao (coming into being). It symbolises Papatuanuku, the earth-mother, the sustainer of all living things, and thus both the land and active forces.
WHITE represents Te Ao Marama (the realm of being and light). It symbolises the physical world, purity, harmony, enlightenment and balance.
The spiral-like KORU, symbolic of a curling fern frond, represents the unfolding of new life, hope for the future and the process of renewal.
