At present this is a nondescript area (see above Google satellite view), basically just an expanse of asphalt and few are likely to encounter it unless they walk from the Grand Car Park to Mahara Place.
Frater Lane itself isn’t much different. Vehicle access to it from the Main road is controlled by a gate.
Nevertheless, the council has decided to pretty it up somewhat, mostly with a modest rectangle of (Maori design?) paving as shown in sketch form in the third pic.
This is scheduled to be done next month.
