"Yeah, it would be nice. It would be very good if they could. And it's also shown that people don't really mind paying 10c extra for their packaging to be eco-friendly."

News of Dominic's sushi success comes a day after new research revealed New Zealand households throw out 1.7 billion plastic containers in their rubbish and recycling bins each year.
The research, carried out by the Waste Management Institute, also found that almost 40 percent of plastic bottles and containers that could be recycled actually ended up in landfills.
