The National Party has set up hoardings around the country to support a series of highway projects that it says would improve safety and promote stronger regional economies.
The Government says it is a "cynical" move, and its own road safety plan ensures a larger number of roads will be safer, rather than focusing on "a handful of gold-plated expressways".
The National Party hoardings, coinciding with busy holiday traffic, are up or going up in Wellsford and Te Hana (Northland), Te Puna (Bay of Plenty), between Otaki and Levin, and north of Ashburton, north of Christchurch, and between Rolleston and Rakaia (Canterbury).
The hoardings are designed to take advantage of clogged roads over summer. The series near Wellsford has three messages: "We know this traffic is a real pain"; "National was building a 4-lane highway here"; "but Labour cancelled it".
Last election National promised eight roading projects - including Mill Rd in South Auckland, Auckland's east-west link, and a Napier-Hastings four-lane expressway - saying they are crucial to save lives and improve regional economic development.
