The Department of Conservation is asking energy provider Alpine Energy to put a net over its Aoraki/Mt Cook substation to prevent more native birds being electrocuted.
A member of the public saw a kea die at Alpine Energy's Unwin Hut Substation several weeks ago and reported the incident to the department.
DoC's Aoraki/Mt Cook programme manager Shirley Slatter said five kea and a native falcon have been found dead inside the compound in a 12 day period.
Mrs Slatter said the department would like to see a net used to keep birds out of the substation and is waiting to hear back from the company.
In the meantime, DOC has sprayed the substation with a kea repellent.
