The public-private partnership incorporated society is dedicated to controlling or eradicating the biodiversity-suffocating pest on 73,000ha of Wakatipu land.
Chairman Peter Willsman, of Queenstown, said he happily reported ''that the incredible gains in understanding the challenge, developing strategies, new technologies, mobilising people and investing financial resources are showing positive signs of preserving the landscape, flora and fauna entrusted to our community.''
A total of $893,000 was invested in control work in the four years before the group launched, while $1.9 million has been invested in pulling, cutting and spraying wildings in the four years of the group's existence.
The 2012-13 WCG financial report showed $385,637 was invested in wilding control.
More than 230ha of private and public land was cleared of the introduced pest by ground crews, spot spraying and boom spraying operations over the past year. The largest operation involved 70ha on Ben Lomond and Bowen Peak.
About 1000 natives were planted where pines were removed at Roaring Meg.
Mr Willsman applauded the work of volunteers in clearing pines, whose ''gifts of sweat and time'' amounted to $117,510 over 3917 hours.
Attendees saw a presentation on the progress of wilding control across Coronet Peak Station, since a company believed to be connected with record producer Mutt Lange, the former husband of singer Shania Twain, bought the land in 2011.
Mr Willsman will share the role of chairman with Grant Hensmen after a unanimous election. Grant McLennan was elected to the executive.
Treasurer Blair Devlin stepped down.
The WCG's financial matters were likely to be managed by accounting staff in the Queenstown Lakes District Council, one of 29 partners in the group.
The group's motto is: ''We don't hate the trees, we love the scenery.''
