Poi E, Tonight, 8.30pm, Maori TV

Poi E might have seemed like something of a novelty record when it hit the airwaves in 1983, but it soon became a favourite in lounges, schoolyards and on dance floors across the nation. Christchurch-born director Tearepa Kahi’s (Mt Zion) lovingly crafted, intimate 2016 documentary captures the anarchic spirit of the song and its creator Dalvanius Prime. The juxtaposition of archival footage with modern-day recollections is expertly bridged by an extended audio interview with Dalvanius, made a couple of years before his death in 2002.
