In 1991, a new landfill was opened in Grenada, with direct access via an overbridge to the adjacent motorway.

A road extension would give Newlands and Paparangi access to the motorway, but the Grenada Village Progressive Association was concerned about any increase in traffic and car speeds.

From 1994, the WCC consulted with residents, and in 2009, the "Mark Avenue Extension" connecting the two roads was opened by the Mayor.

The new subdivision was called Hunter Hills, and future roads would give access to the Lincolnshire Farms development.

Development slowed in the 1980s with the rise in oil prices, but continued steadily over the next twenty years.
