The christchurch City Council has made bus rides free so people working in essential services can get around....
... but then cut the operating hours so nurses can no longer use them to get to morning shift or get home from afternoon shift.
Well that sucks. OTOH it should be easier to get a park. Ask Council if they'll allow indefinite / unmetered parking near the hospital.
In the middle of a highly infectious respiratory disease pandemic, I wouldn't feel comfortable to be on a bus full of nurses / doctors / hospital workers. As well as being essential, they're also probably workers with the most risk of becoming infected.
