Potential immigrant's question regarding rent

Hello, everyone! I am a Canadian seriously considering moving to New Zealand with my partner, and I'm doing some research. We are trying to find an affordable place to initially move to.

Looking online, the consensus is that Christchurch is generally the most affordable. I went online and checked the Regional Economic Activity Web Tool, and was surprised to find that y'all are paying $513 a week for rent on average. That is more than double the rent I am currently paying.

My question is this; am I missing something? Am I misinterpreting the information in some way? Because based on the economic situation in my country, $513 a week is untenable.
