Photo: 123RF NZTech's Digital Skills Aotearoa survey found firms were not doing enough to upskill their staff, leaving a lack of experienced workers to fill complex digital technology roles. About 100,000 people worked in digital roles in New Zealand, NZTech chief executive Graeme Muller said. "Companies spend less than 10 percent on upskilling." In 2019, more than 80 percent of the skilled workers needed to fill jobs in the sector came from overseas, he said. About 4000 to 5000 new digital technology workers were needed in New Zealand each year. Similar numbers of students were trained and 3863 immigrants also gained visas for IT work in 2019 - but gaps still existed for highly skilled IT staff, the survey found.
