Is 68k a good salary to live in Auckland?

I live in Auckland and work as an Architectural technician who has been in the industry for around 8 years, I was on 45k in first 5 years of my career and bumped up to 68k two years ago working for the same company. I do project coordination, draughting, renderings, Council lodgements, RFI's, in residential/commercial sector wearing multiple hats.

Recently bought a small house, and got a mortgage to pay and inflation seems to be getting worse. Just want to know if this is below the average salary in my industry?

Edit: not 55k but 45k for the first 5 years in the company
