Auckland couple Fire and Sonia Fonua are transforming pieces of Tonga koloa (treasure), such as ngatu and ta‘ovala, into jewellery, Stuff reports. Inspired by a visit to Auckland Museum, where Pacific artefacts were tucked away in a basement out of public view, The Fonuas have run Koloa Jewellery from their Glen Innes home since 2018. “We just got thinking about how our children could see it and appreciate it too, instead of storing it away in a basement,” Sonia said. New Zealand celebrates Tonga Language Week from September 4 to 10.
