State highway construction dust monitoring in New Zealand: Current practice and lessons learned
Construction dust impacts are a significant potential environmental effect of state highway construction. In the designation and approvals stage of state highway projects in NZ, management plans are the key tool for showing how environmental effects will be managed, including construction air quality. Through a recent case study, this discussion reviews current practice in NZ state highway projects in relation to managing construction dust emissions and considers the effectiveness, benefits and limitations.

The development, use and value of a long-term on-road vehicle emission database in New Zealand
Vehicle emission standards and management options are continually improving but, with ambient levels of some vehicle-related pollutants remaining stable or increasing in many urban environments, concern is growing that theoretical emissions reductions are not translating into real-world emissions reductions. In this paper we describe the development of the Auckland database, and the important features which make it a valuable research and regulatory tool for managing vehicle emissions in New Zealand.

Trends in air quality impacts from state highways in New Zealand 2007-2012

This paper describes the key features of the NZ Transport Agency Network, reviews the trends seen in the data since monitoring commenced in 2007, highlights some of the logistics involved and indicates future plans for the programme. Emissions from the Network are assessed annually using passive sampling data gathered at selected sites with nitrogen dioxide (NO2) taken as a general proxy for motor vehicle-related air pollution. The overall aim is to see a decreasing trend in NO2 concentrations.

Cold start emission modelling for the Australian petrol fleet
Cold start vehicle emissions are excess emissions due to fuel-rich combustion in the engine, increased friction, and reduced emission control efficiency. Given the growing importance of cold start emissions with respect to motor vehicle emission inventories, it is essential to use accurate cold start emission factors for Australian conditions. This paper presents and discusses the approach that was taken to create cold start emission factors for COPERT Australia, a new software for Australian conditions.

The use of a land use regression model to predict NO2 air pollution in two small areas of Auckland
Land-use regression (LUR) modelling is widely used in many parts of the world, especially in Europe and North America. In this study, LUR was used in two small areas of Auckland: Otahuhu and Mangere. Adjusted R2 figures of 0.72 (Mangere) and 0.44 (Otahuhu) were comparable with other studies. The low R2 found for Otahuhu may relate to the size of the monitoring area (3.5 km2), whereas the Mangere area was ten times larger (35 km2).
