Sir Markus Dunajtschik KNZM (born 1935) is a New Zealand businessman, property developer, and philanthropist.

With his partner, Dorothy Spotswood, he donated $53 million towards the cost of Wellington's new children's hospital, Te Wao Nui, which was opened in September 2022.

[1] In the 2023 New Year Honours, Dunajtschik was appointed a Knight Companion of the New Zealand Order of Merit, for services to philanthropy.

[3][6][4] While studying in Reutlingen, Dunajtschik ended up living in a home for disabled people, since it was difficult to find accommodation in post-war Germany.

He states that this experience made him appreciate having a healthy mind and body and gave him insight that mentally or physically disabled people should be supported by those who are able.

Dunajtschik moved to Canada[4] and spent five years travelling in South America, Australia and New Zealand.

[8] Dunajtschik stated in 2011 that he only invests in properties located between Wellington Railway Station and the Basin Reserve.

The main tenant, Inland Revenue, then evacuated its 2000 staff from the building after an engineering report raised concerns about earthquake resistance.

[17][18] The building was strengthened during 2022,[19] and Dunajtschik said that receiving the new code of compliance from Wellington City Council was the highlight of his year.

Initially approached for a donation, Dunajtschik declared that he could build the hospital himself more cheaply and quickly than if it was left up to government.

[8] Dunajtschik was appointed a Knight Companion of the New Zealand Order of Merit in the 2023 New Year Honours, for services to philanthropy.

Dunajtschik had founded the club after a trip overland by motorbike from New Zealand to Europe in 1955, before he decided to settle permanently in Wellington.
