8.4 Roads<br />

With respect to roads, there is again no universally agreed, unambiguous target. For<br />

our analysis here we assume that all necessary basic roads are already in place, but<br />

that additional welfare gains would come from sealing currently unsealed roads, thus<br />

increasing their reliability and load carrying capacity. We estimate the trend<br />

relationship between the proportion of roads which are paved and per capita GDP.<br />

This is shown in the figure below.<br />

As in the case of telecommunications, we define the target in terms of reaching the<br />

trend in the relationship between the proportion of paved roads and per capita GDP.<br />

We then convert the target proportion into kilometers of roads that require sealing.<br />

<strong>The</strong> unit cost of sealing a road is estimated at US$4.7 per square meter. Assuming<br />

average width of 3 meters, this translates into $US14,100 per Km 24 .<br />

GDP per Capita<br />

Fiji, Marshall Island, Palau and Samoa appear above the trend line, and so already<br />

reach the required standards.<br />

24 <strong>The</strong> cost is based on the average cost given by Transit NZ in its “Elemental Cost Database” issued in March<br />

2005, of NZD34. It includes different types of sealing processes.<br />
