Waihanga Ara Rau Construction and Infrastructure Workforce Development Council has completed the review of the unit standards listed above.

 

Date new versions published                                                               April 2022

 

Planned review date                                                                              December 2026

 

Summary

 

Waihanga Ara Rau Construction and Infrastructure Workforce Development Council reviewed unit standards in the Wastewater Treatment domain as part of a scheduled review.  Consultation with industry occurred by email and via the Connexis website.  Stakeholders recommended updating the legislation and including a statement on Te Mana o te Wai.  Both recommendations were actioned.

 

Main changes

·      Guidance Information was updated in all unit standards to align with changes to water regulation.

·      A theoretical outcome was removed from 11 unit standards at level 5 in order to focus assessment on the practical outcomes.

·      Seven unit standards were designated expiring because of low usage.

 

The last date for assessment of superseded versions of Category B unit standards is December 2023

 

Category D unit standards will expire in December 2023

 

Detailed list of unit standards – classification, title, level, and credits

 

All changes are in bold.

 

Key to review category

A

Dates changed, but no other changes are made - the new version of the standard carries the same ID and a new version number

B

Changes made, but the overall outcome remains the same - the new version of the standard carries the same ID and a new version number

C

Major changes that necessitate the registration of a replacement standard with a new ID

D

Standard will expire and not be replaced
