"Investing in high-tech optical sorters will make for safer workplaces and speed up the sorting process to separate different materials, such as paper and plastics."
Sage said the investment in waste infrastructure would help ensure a better recycling and resource recovery system, with an important focus on the creation of new jobs.
"Internationally the experience is that there are more jobs, and more skilled jobs, in resource recovery than in old-fashioned waste collection and disposal to landfill," she said.
The $36.7m is part of the $124m the Government previously announced it was investing from the Covid-19 Response and Recovery Fund in a number of waste infrastructure initiatives across the country.
Local Government New Zealand president Stuart Crosby welcomed today's announcement.
"Our communities have consistently been calling for urgent action on waste and recycling, and the Government is hearing that and responding.
"LGNZ is looking forward to working with the Government on a strategic plan for waste. This will be critical when the additional funding comes on stream through the waste minimisation fund.
"A strategic approach will help to give us the scale we need to economically process waste and recyclables onshore," Crosby said.
"We look forward to working with the Government to move towards collecting the standardised materials and to identifying and removing any blocks in the way."
