If you have a (part-time) job or paid internship in the Netherlands with which you earn more than 150 euro per month, you need to take out a basic healthcare insurance (basiszorgverzekering).
You can request this insurance via the website of AON or with another insurance company. Information on other insurance companies can be found on the website Zorgwijzer.
During your study period at TU/e you may receive a letter from the Dutch National Health Care Institute (Zorginstituut Nederland). If you receive this letter, you MUST ALWAYS respond!
You will find instructions on how to respond to this letter on the pages of the Study in Holland website.
