Animal Control Products has explored the option of building a plant to manufacture 1080 in New Zealand.
But the State Owned Enterprise says at present there is no need for the plant, while 1080 can still be sourced from the United States.
In a letter to the Primary Industries Minister, Animal Control Products chair Derek Kirke said the only proved source of quality 1080 powder is from a small manufacturer in the United States.
The letter, obtained under the Official Information Act, also says that the risk of adverse legislation affecting the 1080 supply from the US remains relatively low.
Lobbyists in the United States have been trying unsuccessfully for years to pass a bill to ban 1080, and shut the factory that makes the poison.
Mr Kirke has told the minister that on that basis there is no present need to construct a plant to manufacture 1080 powder in New Zealand.
But he said the company would continue to keep a buffer stock of 1080 to protect supply.
He said that at the end of last year the company had a stockpile of about nine tonnes, or $1.8 million worth of 1080 powder.
The Animal Health Board is one of the biggest users of 1080 in New Zealand, using it to control bovine tuberculosis in wildlife.
