The future of a historic sanctuary on Auckland's doorstep that has been up for private sale looks to have been secured after the Government stepped in to boost a joint bid.
Glenfern Sanctuary is on Great Barrier Island's Kotuku Peninsula and inside a rodent-proof fence.
It has become a haven for native animals including the black petrel, pateke (brown teal), North Island robin, kaka and chevron skink.
Conservationists have hailed the news that the Government will put up money to ensure the 80ha property is not sold to a bidder unwilling to retain the sanctuary.
