Explanatory notes
1
Organisational requirements refer to instructions to staff on policy and procedures
which are documented in memo and/or manual format and are available in the
workplace. These requirements include but are not limited to – site specific
requirements, company quality management requirements, hygiene, health and
safety, regulatory and legislative requirements.
2
Laboratory accreditation in this unit standard refers to the programme for the
accreditation of New Zealand dairy industry and associated testing laboratories as
defined by MAF.
3
Registration - All dairy laboratories that test diary products and produce for food
safety, truth of labelling, and export certification are registered by MAF Food in
compliance with the Dairy Industry Regulations, 1990.
4
Routine explanations and reports may be in everyday workplace language including
mathematical language and some commonly used technical terms, be presented
orally, be presented in writing using standard format, proforma, charts and diagrams,
include mathematical and other information from several sources.
5
Assessment is to be made in the industry context, and should take place primarily
on-the-job under normal working conditions.

Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
