Gavin O'Brien is a senior lecturer in Product Design at Otago Polytechnic and has a Masters degree in Applied Science from Otago University. Gavin will be discussing his studies based on the work of Ernest Hayes as an industrial designer and Hannah Hayes as a marketing pioneer. The records of Hannah's sales exploits by bicycle into the Maniototo in the late 19th Century are a fascinating insight into the agricultural landscape of the time. Ernest's legacy is the Hayes 'chain grip' wire strainer patented in the early 1920's and awarded a New Zealand design award in 1981. This item is still being widely sold, practically unchanged almost a century after it's inception. Together, Ernest and Hannah pioneered product design and marketing within the South Island and are an fascinating example of kiwi ingenuity.
