"Local businesses will have an improved playing field, while consumers will still have choice, but offshore sellers may revisit their pricing."
The Russells got into e-commerce after they bought Biogrow, a horticultural business specialising in providing fertile, biodegradable pots to commercial growers, in 2013.
Ms Russell said Biogrow initially dealt in commercial quantities, then saw opportunities in also selling directly to retail consumers online.
However, when they investigated storage and distribution options, they realised there was a niche in offering a service to small e-commerce companies and set up TADS.
"There's been a huge increase in people starting up part-time, working from home," she said. "When we looked at the cost and practicalities of leasing smaller storage units, it was not sustainable and did not take into account the time and disruption to travel to them, or the extra expense when stocks are low.
"Then there is the hassle of hiring part-time staff to help with dispatching when volumes can vary largely from season to season."
Ms Russell said in their experience large freight-based companies preferred bulk goods and were not prepared to take on smaller clients with smaller individual items.
TADS is not tied to any one freight or courier company and has been able to negotiate competitive volume rates.
The company's services include helping with importation, Ministry of Primary Industries container clearances, storage, logistics and distribution.
"Tauranga is an incredible place to base a logistics and distribution business as it has the best container port in the country and fantastic transport links.
"People are contacting us nationwide and from overseas."
Derek Roser, director of Circle Management Services, who provides advisory services to the Tauranga Chamber of Commerce, said there was place for TADS.
"They've identified a niche market that isn't being serviced," he said.
"They provide support for the growing number of small importers without major logistics departments who require a small amount of flexible storage and in-country distribution."
Brennan Sexton, the founder and managing director of Melbourne-based online retail store network Niche Now, uses TADS to distribute its Universal Remote Controls.
The company initially successfully test launched its product, using a courier to ship express from Australia to New Zealand.
"We then decided to go into an agreement with TADS to distribute our products, which costs about 10 per cent of what it was costing during the soft launch."
