Inconsistent terminology across national direction instruments on quarrying and mining
The NPS-FM, NPSIB and NPS-HPL have inconsistent terminology for quarrying and mining activities. For example, “quarrying activities” are referred to in the NPS-FM and NES-F, whereas the NPSIB and NPS-HPL use “aggregate extraction” (undefined). The definition of quarrying activities in the National Planning Standards includes both the activity of quarrying as well as the ancillary activities needed to support it.39
Similarly, the NPS-FM and NES-F refer to “the extraction of minerals and ancillary activities”, whereas the NPSIB and NPS-HPL use “mineral extraction”. Neither term is defined. The NPS-FM term covers all the activities needed to support mineral extraction and ensure a viable consent pathway.
Inconsistent gateway tests and consent pathways for mining and quarrying
The national policy statements provide consent pathways for specific purposes (eg, quarrying and mining) and regulate certain activities40 where they adversely affect SNAs, HPL and wetlands. The consent pathways allow consent authorities to recognise government goals – including social and economic wellbeing and the need for resources – while managing adverse effects of activities on SNAs, HPL and wetlands.41
To access these consent pathways, a consent application must show a need exists for the adverse effects on protected environments to occur by meeting certain ‘gateway tests’. If the application meets these gateway tests, a proposal’s adverse effects can be managed using an effects management hierarchy. For example, the gateway tests for quarrying in or around a wetland under the NPS-FM and NES-F are that the aggregate will provide significant national or regional benefits, and there is a functional need for the quarry to be in that location.
The NPSIB has different gateway tests relevant to SNAs, including that there is an operational or functional need, and that the proposal provides significant regional and or national public benefits that could not otherwise be achieved using resources within New Zealand. The NPS-HPL applies three gateway tests similar to those in the NPSIB.
39 The National Planning Standards define ‘quarrying activities’ as “the extraction, processing (including crushing, screening, washing and blending), transport, storage, sale and recycling of aggregates (clay, silt, rock and sand), the deposition of overburden material, rehabilitation, landscaping and cleanfilling of the quarry, and the use of land and accessory buildings for offices, workshops and car parking areas associated with the operation of the quarry.” Ministry for the Environment. 2022. National Planning Standards. Wellington: Ministry for the Environment. p 62.
41 For example, the wetland provisions control vegetation clearance, earthworks and water take, use, discharges for mining and/or quarrying.
42 SNAs and wetlands are matters of national importance under section 6 of the RMA and require consenting authorities “to recognise and provide for” them in decision-making. HPL is listed under section 7 of the RMA and requires consenting authorities to have “particular regard” for HPL in decision-making.
