* Analysis method not accredited by International Accreditation New Zealand
~ Analysis is outsourced to another laboratory - prices are subject to change
1: e.g. Tokoroa
2: e.g. Hamilton - most outsourced analysis
3: e.g. Auckland - outsourced MST analysis
4: Applies to work that must be carried out after-hours - weekends, public holidays, mid-week after-hours callouts. This includes samples submitted on Friday or the day before public holiday for E coli (testing timeframe is regulated).
5: Entering clients field results into Laboratory Information Management System
6: Subject to change once IRD release new rates mid-year
