Waihanga Ara Rau Workforce Development Council (WDC) has completed the review of the unit standards listed above.
Date new versions published February 2023
Planned review date December 2027
Summary
Waihanga Ara Rau Construction and Infrastructure WDC identified a group of unit standards due for review. Stakeholders were consulted by email and through the Waihanga Ara Rau website, and feedback was discussed by a technical advisory group.
Some unit standards, although they had no or low usage in the previous five years, were identified as useful to industry. These were maintained for potential use in micro-credentials.
Main changes
· The standard setting body was changed to Waihanga Ara Rau Construction and Infrastructure WDC.
· Guidance information was updated to align with current legislation, published Standards, or to the current version of the Electricity (Safety) Regulations where appropriate.
· The credit values for unit standards 17056, 17058, 17059, 26739, and 26741 were reduced to better reflect the notional learning hours.
· Thirteen unit standards were designated expiring due to low usage.
The last date for assessment of superseded versions of Category B unit standards is December 2025
Category D unit standards will expire at the end of December 2024
