His Churton Park-based business had other products and concepts that were being developed, such as Inflatable signage, junior rugby posts and softball nets.
Rugby was the fastest growing sport in the US and believed there was a market for the product.
He was so busy taking the Bocce products around the world, he did not have time to market his other products and welcomed business partners to take them on.
The value would come from investors experience and not their money, he said.
"It's my ambition to have Packaworld branded products everywhere in the world but to do that I will need a better distribution networks. It may be time to bring people on board to support and help with my ambitions."
Packaworld International, which has been in operation since 2013, was making money that was invested back into the company.
Roberts, who has no employees, said a key driver was the ability to run the business himself.
"It's still good to have people around you as part of a business, so I have a good accountant and lawyer and bring in people with expertise when I need them."
The products are manufactured in China and the maturity of his business operation has seen him outsource warehousing, stock and orders.
The New Zealand market was limited and it took him about three years to figure out where to go.
"I realised the way to grow this business was to create a brand that someone will pay money for. My exit policy - but not yet because I'm having fun - is to build a brand that people will pay money for."
The Special Olympics was a trigger point for the international expansion, which started a wave of interest in his products.
He was contacted by Wicker Park Bocce Club in Chicago, which is now the United States distributor.
"Relationships are key in business and I like integrity. These guys were honest, trustworthy, they had my product at the forefront. I have now helped them build a business - the American Bocce Company, which has 1500 registered people who play in leagues."
He was amazed the impact his storage solutions has had on the world, he said.
