The Otago Settlers Association history prize recipient has spent the past three weeks investigating such subjects at Toitu Otago Settlers Museum.
The association has offered the prize for the past 12 years to leading second-year history students at the University of Otago.
The prize includes a six-week paid internship at the museum during which top students undertake a series of projects, including historical research.
Mr Rawcliffe (20) yesterday gave a talk on his recent work to about 15 association members, at the museum.
He looked into the departure from Dunedin of well-known companies and brands, including Penrose's, Shacklock, as well as Carisbrook and St George jams.
Mr Rawcliffe said he was ''enjoying researching, sourcing objects and images'' linked to ''icons ... that no longer exist in Dunedin''.
It had been ''interesting to look at businesses and industries that have vanished over the last few decades'', he said.
Museum curator Peter Read is working with Mr Rawcliffe, whose project will help with research and other preparation for ''refreshment'' of the 20th century timeline cases, which will be undertaken towards the end of this year.
The museum's 20th-century display area includes 10 interpretive display boxes, each covering a decade, and the refreshment will include changing some of the images and the interpretive commentary.
