September 2023. Aotearoa New Zealand's first digital public artwork, HALO, is suspended high above the legendary harbour Te Whanganui-a-Tara in the capital city Wellington. The stone monument proposes a circle of unity connecting earth, sky and sea. At the leading edge of creative technology, this giant sculpture is viewed in 3D, at full scale in real time and space. It disperses sun and moon-light, and casts a shadow on the sea. Created by each person using their mobile phone or tablet at three site-specific locations, HALO is revealed through extended reality. Visitors to the waterfront can scan QR codes to view the artwork on Te Aranui o Pōneke / The Great Harbour Way – from the Te Papa Tongarewa Museum of NZ Bush Walk harbour-front terrace, and from two seaside promenade sites: in front of Te Papa, and outside the Star Boating club. Commissioned by the Wellington Sculpture Trust as a 40th anniversary gift to the people of Wellington NZ, look for signs at Te Papa and on the harbour’s edge, and step into the Metaverse!
