The NZ Extractive Industries Training Organisation (EXITO) has completed the review and revision of the unit standards listed above.  The revised standard is shown in bold.

 

Date new versions published                                                          May 2010

 

Planned review date                                                                           December 2015

 

Summary of review and consultation process

 

These standards were amended to better align with gas distribution industry requirements to separate service laying and mains laying skills in different qualifications.  The National Certificate in Gas Network Construction (Pipelaying) (Level 3) [Ref: 1022] was found to be unachievable in some workplaces, so it was reviewed to remove restrictions.  As a result of that review the more advanced skills relating to mains laying will transfer to a proposed new level 4 qualification.

 

A specialist group of advisors, providers, and assessors met in July 2008 to review the standards and the qualifications, which were then widely distributed to industry whose feedback clarified the content.  Consultation also took place in July with the infrastructure pipelaying advisors at InfraTrain New Zealand and some standards required amendment to apply to both industries.  The reviewed standards were endorsed by the gas industry sector advisory group in November 2008.

 

Standard 10969 was revised to remove entry requirements which caused a recursive relationship with a proposed replacement qualification.

 

Main changes resulting from the review

 

·        Titles for standards 10968, 19546 and 19547 were amended to better reflect content.

·        Levels for standards 10968, 10972, 10981, 10986, 10988 and 23087 were increased to better reflect the degree of applied knowledge.

·        Credits for standard 19547 were increased to better reflect learning and assessment requirements.

·        Entry requirements of some standards were updated to meet gas industry requirements and, as all the standards have health and safety embedded in them, to ensure that only prerequisites critical to health and safety are retained.

·        Special notes of some standards were updated to include the Approved Code of Practice for Safety in Excavation and Shafts for Foundations.

·        Performance criteria were added to include key outcomes, and elements amended.

·        Range statements were amended to reflect current industry practice.

·        Standard 10985 was replaced by standard 25608.

·        Three new unit standards were developed for knowledge of specific operations in gas distribution networks.

 

The unit standard categorised as category C will expire at the end of December 2012.

 

Impact on existing provider accreditations

 

None.

 

Impact on existing qualifications

 

Qualifications that contain the reviewed standards or classifications are tabled below.

 

Affected

The qualification lists a reviewed classification (domain or subfield) in an elective set

The qualification lists a standard that has changes to level or credits

The qualification lists a C or D category standard

Not materially affected
