Review of Drainlaying qualification


National Certificate in Drainlaying [Ref: 0077]


The Plumbing, Gasfitting and Drainlaying Industry Training Organisation Limited has completed the review of the qualification listed above.


New Qualification


National Certificate in Drainlaying (Design, Management and Supervision) (Level 5) [Ref: 1831]


Date new version published                                                             April 2012


The next qualification review is planned to take place during 2012.


Summary of review and consultation process


This qualification was reviewed in order to ensure alignment with the competencies of a licensed drainlayer as reviewed through industry consultation.


Feedback indicated that some competencies in the reviewed qualification undertaken by apprentices should be included in a new Level 5 qualification which has been developed in parallel with the review of National Certificate in Drainlaying (Level 4) [Ref: 0077].


Ten organisations with consent to assess met with industry moderators and two affected standard setting bodies (SSBs) to comment on proposed changes to the qualification.  Endorsement of the reviewed qualification was provided by the affected SSBs.  An onsite feedback session was held with Canterbury assessors.  Industry practitioners from large commercial firms to sole traders involved in domestic drainlaying work and the SSB's technical moderators provided detailed review and advice.


The draft version of the qualification was endorsed by the National Industry Advisory Group (Drainlaying), Plumbers, Gasfitters and Drainlayers Board and NZ Master Plumbers Association, in February 2011.


This qualification can now lead to the National Certificate in Drainlaying (Design, Management and Supervision) (Level 5) [Ref: 1831], which has been registered this month.


Main changes resulting from the review


Some unit standards were replaced and/or removed; unit standard titles, levels, and credits were updated to reflect changes made after they were reviewed; new unit standards were added to the qualification; and the title was changed.

Changes to structure and content

·      Title of the qualification was changed to include the level and a descriptor (Installation) in order to better reflect the graduate profile of drainlayers.

·      Expiring Core Health unit standards 6400, 6401, and 6402 were replaced by unit standards 26551 and 26552; safety unit standard 18426 was substituted by unit standard 17599 to require learners to demonstrate capabilities in confined space entry rather than just demonstrate knowledge; expiring unit standard 1101 was replaced by unit standard 27336 to replace reference to obsolete installation technology with knowledge of current technology; expiring unit standard 1107, and unit standard 21946, were removed from the qualification.

·      Five new unit standards (27332-27336) were added to the qualification, two of which (27332 and 27334) are required for eligibility for licensing as a drainlayer.

·      Unit standard 25425 was added to the qualification to assess numeracy skills required by industry.




People working towards version 6 of this qualification may either complete the requirements of that version by 31 March 2015, or transfer their results to version 7.


The last date for entry to programmes or courses for version 6 is 31 December 2012.
