Approved polyethylene welders need to be suitably experienced individuals who have relevant experience and skills and who undertake regular training.

All welding work must conform to the standards set out in the Council's Construction Standard Specifications, and all materials used must be approved and acceptable to the Council.

To become approved, applicants need to provide evidence to Christchurch City Council that they have:

  • Experience in welding polyethylene pipe in accordance with industry best practice, and are familiar with Council standards and specifications.
  • A suitable welding certificate that is not older than two years.
  • Health and safety systems in place.
  • Quality assurance systems in place.
  • Public liability insurance cover.
  • Resources to carry out the work quickly and efficiently.

Applicants and Council-approved PE welders also agree to be bound by the terms and conditions [PDF, 396 KB].

Apply to be an approved PE welder

The non-refundable application fee can be paid at any Council Customer Service Hub or by calling 03 941 8999.

On-site technical assessments are required to ensure that the applicant has the necessary experience, technical skills and resources to carry out the welding in accordance with Council regulations and relevant AS/NZS standards.

Approval will be given in writing only and is only awarded to the individual and not to commercial entities. It is not transferable and can be withdrawn by the City Council upon non-compliance with the rules as outlined in the terms and conditions.

Approval is given for a two year period which aligns with the PE welding training. Approved welders will need to renew their approval every two years.

Please note that due to the large number of applications and the associated on site assessments the current turn around time is a minimum of two months. 

Enquiries about the scheme can be made by emailing Council on pe@ccc.govt.nz.
