I worked as a teaching assistant and PhD student in Dunedin, Otago. Depending on the department, the culture is different. salaries for PhD and PostDocs are good and fair. However, job security after graduation is an issue. The administration workflow is amazing. Very smooth and quick in responses.
I am a full-time student working part-time for the university. I am relatively well-respected by my colleagues and the students I teach alike – with each hall of residence varying. They have set pay scales for each level of education (eg. undergraduate, graduate, masters) for hourly tutoring pay. Undergraduate is ~$19p/h for preparation and delivery of tutorial.
