The Best Short Nursing Course or Program to Study

[Angeline]

Hello, everyone. I'm from the Philippines. And I am currently studying a 6-month caregiving course. I plan to work at a nursing home in New Zealand after some time. But before that, I need to study a nursing course/program so that I may be accelerated at work. May I ask what are the best nursing courses or programs that are less than 4 years to study?
