General Ballance Agri-Nutrients Limited is one of New Zealand’s leading fertiliser specialists, with manufacturing plants located in Whangarei, Mount Maunganui and Invercargill. In addition, the company owns the ammonia-urea manufacturing plant at Kapuni in Taranaki, and Super Air, one of the country’s largest agricultural aviation companies.

Ballance is a 100-percent farmer-owned co-operative, with some 18,000 shareholders throughout New Zealand. It was officially launched in 2001, the final step in a series of company amalgamations and alliances that saw regional fertiliser co-operatives come together under the umbrella of what was then Bay of Plenty Fertiliser.

Today, Ballance is a truly national company, with staff located from the Far North to the Deep South. The company places a strong emphasis on delivering value to its shareholders and on the use of a scientific approach to plant nutrient management

January 24, 2007 - Fertiliser producer Ballance Agri-Nutrients shifted two massive tanks used for sulphuric acid storage yesterday as part of a $1.1 million environmental project upgrade.  At the Awarua factory site, contractors Donaldson Construction and Smith Cranes carefully moved the empty 35-tonne steel tanks, which have a capacity of 1000 tonnes of acid, to concrete pads.  Operations manager Neil Miller said that in the extremely unlikely event the tanks failed, acid would be contained by the concrete pads and within 1.8m high concrete walls that were being built around them.  Four other smaller tanks, built in the 50s, were being decommissioned and would be sold off.  The project, 12 months in the planning, was a continuation of Ballance's environmental storm water recycling project, he said.  Last year Ballance won a top corporate award from Environment Southland for a 10-year effort to clean up its Awarua site.  "The company has spent a lot of money on proactive environment projects. With time these changes would be forced upon us but we are doing it beforehand," Mr Miller said.  The sulphuric acid is mixed with phosphate and made into super phosphate for agricultural uses.  Ballance also stores acid in a much larger tank in Bluff, from which trucks transfer up to 20 loads a day in peak season.

March 12, 2002 - One of the biggest tanks ever constructed in New Zealand arrives in Bluff at 9 am tomorrow (Wed March 13) as part of fertiliser company, Ballance Agri-Nutrients Ltd’s $4.5 million expansion plans for its manufacturing plant in Awarua in Southland.Built by Culham Engineering in Whangarei, the 30m X 12m steel sulphuric acid tank with a 12,000 tonne capacity weighs nearly 400 tonne and is the major feature of the company’s multi-million dollar development.Chief Executive for Ballance Agri-Nutrients Ltd, Larry Bilodeau, says the Awarua expansion will enable the company to increase production at the plant and therefore effectively cater for the needs of Southland’s burgeoning agricultural industry.“We are committed to ongoing investment in strategic areas and this expansion recognises the value we place on Southland’s importance in the national agricultural scene,” he says.The expansion has being welcomed by one of Southland’s largest agricultural operators, Mt Linton Station Manager, Paul McCarthy.“With the farming industry experiencing buoyant times in Southland there is a greater need for increased product availability and we welcome Ballance’s decision to expand down here as it will relieve the supply pressure at crucial times in the season,” says Mr McCarthy.The new tank will increase acid capability for the Awarua plant initially from 70,000 tonne to 90,000 tonne and will use imported product from environmental recovery streams.This upgrade will increase superten production capacity for the plant by more than 25% and ensure the company is in a good position to meet the growing demand for this popular fertiliser product.

September 25, 2001
- Ballance Agri-Nutrients' Awarua fertiliser manufacturing site reopened for business yesterday, following a fire last Friday. Ballance Agri-Nutrients South Island Operations Manager, Graeme Bycroft, says fertiliser despatch and sulphuric acid production are fully operational and the Company will restart superphosphate manufacturing operations in mid-October at a slightly reduced rate. Ballance Agri-Nutrients Chief Executive Larry Bilodeau says the site has sufficient stocks of product to cover the next six weeks and two shipments of product from the Company's Northland plant will more than cover the market requirements until the Awarua plant is fully operational. An initial assessment of the fire damage has shown that the blaze damaged one end of the superphosphate plant. The fire was contained to a small area of manufacturing plant and destroyed the plants discharge stack and associated equipment. Mr Bilodeau says the Company has brought a second-hand stack and is currently shifting the temporary stack to the site. It will enable the site to restart manufacturing in mid-October while a new stack is built. He says the plant will initially run for longer hours in order to produce the same weekly fertiliser output. The plant is expected to be back to full capacity by Christmas.
