These increases do not change how we work with you. You continue to have access to:
- Nationwide supply and logistics, with consistent product quality and standards across the country
- Ongoing technical support, clear specification documents, trusted warranties and support for your projects
- Profiles designed for New Zealand conditions, backed by Dimond’s 60 years of experience
Our current Fuel Surcharge is outside of these price changes, and the surcharge will only remain in place during the current fuel price crisis.
If you have active projects, upcoming tenders, or volume commitments you'd like to discuss ahead of 11th May, please contact your sales rep to discuss.
Thank you for continuing to partner with Dimond, we’re proud to work with you to deliver exceptional service to your customers.
Kind Regards,
Damien Sauni
