The Historic Arrowtown Chinese Settlement and the Kawarau suspension bridge are the latest Otago sites to receive the new Landmarks Whenua Tohunga status.
They were chosen because of their significance to the country and the visitor experience they offered.
The Landmarks programme is a joint initiative between Manatu Taonga the Ministry for Culture and Heritage, the Department of Conservation (Doc) Te Papa Atawhai and Heritage New Zealand Pouhere Taonga.
Doc Wakatipu-wai-maori manager Geoff Owen said he was delighted the two sites had been selected.
"The Landmarks Whenua Tohunga programme brings to life the stories of Aotearoa’s past and connects New Zealanders and overseas visitors to the people and places that define our nation.
"The 12 Otago Landmarks sites also provide tourism benefits by giving visitors places to see which are strongly linked by their cultural and heritage value.’’
On Tuesday the first celebration would begin at 10am at the Arrowtown Chinese Settlement, where Chinese Consul-general Wang Zhijian and Queenstown Lakes Mayor Jim Boult would speak before the pou unveiling.
That would be followed by a free guided public walk.
The second event, celebrating the Kawarau suspension bridge, would be held at The Winehouse from 2pm.
Mr Owen said both events were open to the public.
