I did bachelors in computer science in India. Worked for 8 years in IT and management. Applied to master of management program in Canada, and got in. I turned 31 when I was in my first semester of the program. The age is not a problem. A classmate in the same program was in his early 40s. He had a masters degree prior to this program.
The intent matters. In your case you did your BBA in India. Then went to NZ for a Post-Graduate program in business and worked there for a few years. You showed you put whatever you learned into practice, which is important. It shows growth. Then you went back to India and worked. That's good too.
Congratulations on getting into the Post-Graduate program in Supply Chain Management. Did you study SCM as a subject in your bachelors, or your previous post-graduate degree in NZ? I'm asking because it is important that you explain your motivation for studying SCM , and studying in Canada at this point in your life. How is that going to help you grow? These are important questions you need to answer to prove your intent. The one benefit you have (in my opinion) is that you worked in between your degrees. You worked in NZ, and then you worked for a few years in India, before choosing to study in Canada (now).
Make sure your SOP reflects your intent, your career goals carefully. I hope this helps.

EDIT - BTW, what university/college did you get into? That kinda matters too.
