Are there an affordable NZQA Level 7 course for people who has a bachelor’s degree in a non-IT field? AIS is too expensive for me.

I am looking for a one-year course in New Zealand. I found that AIS (Auckland Institute of Studies) offered Graduate Diploma in IT Level 7. But that is expensive for me. Lincoln University and the Ara Institute of Canterbury Institute of Canterbury can not enter without a bachelor’s degree or practical experience in IT.
