Waller said Symbion was the largest pharmaceutical wholesaler and distributor by revenue in Australia.
It supplies around 30 per cent of community pharmacies in Australia and has a 60 per cent share of the hospital market as well as distributing pet products.
Waller said there was an 89 per cent degree of fit between the businesses which meant there would be no cannibalisation through bringing them together.
He also hoped to bring Symbion's technology on board and create a fully automated robotic "supersite" in Auckland.
"It could run the whole national supply chain for the business," he said.
Waller expected that to create more jobs.
The acquisition will mean 75 to 80 per cent of Ebos' revenue will come from Australia. But Waller said he had no plans to shift the Christchurch head office across the Tasman.
Devon Funds Management analyst Phillip Anderson said the deal was transformational for Ebos and the company had paid a good price for the acquisition.
The deal is expected to be 30 per cent earnings accretive and will go through on June 1 provided it gets consent from shareholders.
