Visiting Christchurch for a month without a car, any tips and advice?

Hello everyone,

I'm planning to visit Christchurch for a month from October through to November to work remotely, and go on as many day hikes as I possibly can with the leisure time in between.

I can't drive, so I'll have to rely on public transport; does anyone have any trails, or day trips that are accessible by public transport to recommend?

I've planned to book an Airbnb for the month I'm there, but are there any better alternatives for month long stays?

Any other tips and advice would be much appreciated, thank you in advance 😊🙏
