"She brings a comprehensive and exciting range of skills that will help further build visitor and educational experiences," Mr Francis said.
"Her strong leadership, success with growing teams, and marketing and tourism background will serve us well in the transition to the new management arrangements, growing visitor numbers and providing a world-class customer experience."
Mr Francis said Ms Tickner would work closely with the board and its partners, DoC, Rangitane o Wairarapa and the community, while managing the visitor centre's team of volunteers and staff.
DoC's captive breeding programme will continue at the National Wildlife Centre and the department will carry on with restoration of the 940ha forest, including pest control.
"While it is the end of an era, it is also the start of an exciting new phase for the Pukaha visitor operation, which has been well served by DoC for the past 30 years," Mr Francis said.
Ms Tickner will take up the general manager's role in June.
