Until it Runs Out was filmed over one year in the Māngere inlet and records the ecologies of the Old Māngere Bridge, the construction of an artificial beach on Orpheus drive and the foreshore birdlife. The images were captured on fifty-year-old black and white 16mm reversal stock that reveals signs of deterioration and failing of emulsion.
Randerson also collaborated with environmental scientists from Auckland Council, who dived to attach an EXOsonde instrument for measuring turbidity and other water quality parameters, to understand more about whether the newly created Onehunga beach will be safe for swimming. Sonic interpretations of this water quality data form the soundtrack to the work.
