What does ''to'' mean in this context?

The Helpline was set up ten years ago by the Students Union and it aims to provide new students to the university with a service that they can use if they need information about practical areas of student life that they are unfamiliar with.

This is an inversion and poorly written. You can rephrase it as follows:

The Helpline was set up ten years ago by the Students Union and it aims to provide students new to the university with a service that they can use if they need information about practical areas of student life that they are unfamiliar with.

"students new to the university" can be understood as "students who are new to the university"
