A Hawke's Bay company has recalled its first shipment of drinking water to China after it failed to meet the standard for nitrite levels.
Miracle Water said China's standard for the naturally occurring compound was 0.002 milligrams per litre.
But it said New Zealand's - and other markets' - standards were much less stringent.
The company said it made an error, but there was no safety risk and it has continued to send shipments to China since the recall.
It said it was now checking daily to make sure the filtration process had filtered the water to the appropriate standard for its destination.
