Landowners affected by proposed routes for the Otaki to north of Levin expressway are having one-on-one meetings with roading officials before the public release of the routes next week.
The New Zealand Transport Agency has been showing landowners a high-level map of the routes, and a copy of the map has been leaked online.
The map shows three routes to the east of Levin, and residents near Arapaepae Rd and Manakau look particularly affected.
Residents, commenting on Facebook, have been critical of NZTA for what they see as its "divide and conquer" strategy of talking to landowners individually. A couple of Facebook groups have sprung up to help affected residents share information.
It is understood letters were sent to around 460 affected property owners.
