National Certificate in Gas Network Operations with optional strands in Operations and Maintenance, and Field Auditing

Level 3  Credits 115

This National Certificate is designed for people working in the network distribution sector of the gas industry, and recognises the skills and knowledge required by the New Zealand gas industry for certification as a trade operative in gas network operations and maintenance, and field auditing.

This qualification contains optional standards that are not required for completion of the certificate. However, these may be considered necessary for some employment contexts in the gas distribution industry.

Prerequisite: National Certificate in Gas Industry - Gas Distribution (Level 2) or demonstrate equivalent knowledge and skills.

Special Note
People working in a gas pressure control context will require achievement of the compulsory and elective sections; people who repair gas networks will require the optional strand in operations and maintenance; and people who undertake audits may choose the optional field auditing strand.

For accreditation as an official industry auditor both optional strands are required.
