The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in New Zealand, for both new street additions (left) and the aggregate street network (right).
New Zealand in context: Street-network sprawl of new development
The level of street-network sprawl in new development in New Zealand peaked in 1991-2005. To get a sense of how street development has changed in New Zealand, we can consider three of its most populous regions: Auckland, Canterbury and Wellington. Disconnectivity in the most populous cities in New Zealand follow the same country trend.
The largest city in New Zealand is Auckland, with a population of 1304700 people.

The level of street-network sprawl in new development in Auckland peaked in 1991-2005.
New Zealand in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in New Zealand is Tauranga with an SNDi of 5.01, which is very sprawly. Conversely, the most connected city is Dunedin with an SNDi of 2.37, which is well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Dunedin, Tauranga.
