The Otago Regional Council has given details of two more water bottling permits in the region, as the government moves to increase scrutiny of water exports.
However, the council says it does not believe any bottling is actually taking place.
RNZ earlier revealed Koha Water Limited was trying to sell land in the Southern Alps near Queenstown with a consent to bottle 236 million litres of water a year until 2038.
A 15,000-signature petition presented to Parliament last week by the Bung the Bore campaign called for a temporary ban on bottled water exports.
The regional council said three water permits existed for water bottling in the region.
As well as Koha Water, Green Ocean Group has the right to bottle 10,000 litres an hour, or 87m litres a year, from a tributary of the Clutha River near Cromwell.
And an Alexandra person has the right to take 4m litres a year for domestic water supply, irrigation of a hectare of land and bottling for sale.
The council's chief executive, Peter Bodeker, said any permit holders taking water for bottling would have to notify the council of their water use, and none of them had submitted any information.
Mr Bodeker said the council had not specifically investigated the permits but was confident none of them were being operated.
Last week, Environment Minister Nick Smith said the water taken from aquifers for bottling represented a tiny fraction of the total amount extracted for tap water and irrigation.
Prime Minister Bill English yesterday said the government would ask an advisory group to look into the questions around exporting water, in response to public concern.
The technical advisory group was expected to report back at the end of the year or early next year.
