Explanatory notes
1
All work practices must meet recognised codes of practice and worksite procedures
for personal and worksite safety, and for environmental protection, and must meet
the requirements of current legislation.
2
New Zealand standards relevant to this unit standard include but are not limited to
NZS 3605: 2001 Timber piles and poles for use in building, which is available at
http://www.standards.co.nz. The abbreviation ‘NZS 3605’ is used to refer to this New
Zealand standard for the remainder of this document.

This unit standard is intended for work-based assessment. While all evidence
requirements must be met, some range statements within this unit standard are
indicative and dependent on enterprise and worksite specific equipment, procedures,
and practices.

Definitions
Crook refers to deflection from straightness affecting a maximum of 1.5 metres of the
length of the roundwood product;
Large-end diameter (LED) refers to the measurement of the longest diameter through
the geometric centre of the log at the large end;
Optimisation refers to the skill of determining the maximum commercial use of
roundwood to meet the requirements of production;
Peeling refers to removal of bark and cambium layer by machines fitted with cutter
heads, which follow the natural contours and irregularities of the log;
Pole refers to a naturally round tree stem used to support wiring or used in
construction that is longer than 3.6 metres;
Roundwood refers to round, and part-round, wooden posts and poles that are shorter
than 3.6 metres;
Shaving refers to the removal of bark and cambium layer by machines fitted with
cutter heads, which do not follow the natural contours of the roundwood product, but
do produce a uniform taper;
Small end diameter (SED) refers to the smallest diameter along a pole or roundwood
product, usually found at one end;
Sweep refers to the largest deviation from straightness determined using a logger
tape or other straight edge along the length of the log;
Worksite policies and procedures refer to documented policies and to documented or
other directions provided to staff. These include, but are not limited to, ways of
managing health and safety, environmental considerations, quality, and production,
and must conform to legislation. Examples include standard operating procedures,
company health and safety plans, on-site briefings, and supervisor’s instructions.

Please note
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.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
