In 1947, he unsuccessfully applied to be chair of design at the School of Architecture at Auckland University College. As an unregistered architect he then sought out a partnership with a registered architect. In 1948 he formed the 'Plishke & Firth' partnership with Cedric Firth. Massey House (1951–1957) located on Lambton Quay was their biggest project, with Plischke designing the concept due to Firth being abroad. The partnership ended in 1959 and Plischke joined Robert Fantl in another partnership, but with work drying up in the early 1960s Plischke accepted an academic role back in Vienna, Austria.
