Koru art is a significant motif in Māori art that symbolizes new life, growth, and renewal, based on the unfurling frond of a fern. The spiral shape represents the continuous journey of life, interconnectedness, and a return to the point of origin, embodying strength, peace, and potential. This symbol is widely used in traditional carvings, tattoos, and painted designs, such as those seen on the rafters of wharenui (meeting houses).
