Waste data in New Zealand
SWAP Baseline Programme
The Ministry for the Environment has instituted a Solid Waste Analysis Protocol (SWAP) Baseline Programme to provide solid waste composition information at four indicator sites from around New Zealand. The objective of the programme is to establish generic waste composition data for New Zealand and to provide a basis for designing and interpreting SWAP surveys throughout New Zealand.
The indicator sites to date are:
- Silverstream Landfill - Hutt City Council
- Green Island Landfill - Dunedin City Council
- Matamata Transfer Station - Matamata Piako District Council
- Kaikoura Landfill - Innovative Waste Kaikoura/Kaikoura District Council

The first, intensive part of the SWAP programme is almost complete, with two surveys to be completed shortly. The surveys have been scheduled over two years, with survey times chosen to take into account seasonal and annual variation.
The SWAP Baseline survey programme was as follows:

In addition to the SWAP Baseline data from the four indicator sites, SWAP data has been made available to the Ministry from:
- Wellington City Council SWAP survey programme, two SWAP surveys at the Northern and Southern landfills, survey of rubbish bag and wheelie bin collections and recycling collection system (survey dates August 2002 and February 2003)
- Gisborne District Council - annual survey programme
- Westland District Council - annual survey programme
- Marlborough District Council
Further, less intensive sampling is planned for the future to ensure that representative data is maintained.
2007/08 solid waste audits of indicator sites
To enable the detection of any trends in waste composition over time, the Ministry for the Environment re-surveyed the four indicator sites in 2007/08. The results of these surveys are available in the ‘Solid Waste Audits for Ministry for the Environment Waste Data Programme 2007/08’ report
