Procurement, assurance and verification
Procurement decisions and sustainability claims need sound evidence. Tonkin + Taylor helps clients assess supplier performance, make informed purchasing decisions, and ensure that claims about products, services, and operations are credible and defensible.
Our approach is practical and proportionate, focusing on the risks and requirements that matter to your organisation. We help identify evidence gaps, strengthen controls and ensure claims accurately reflect what the data supports. This reduces the risk of greenwashing and builds confidence among customers and other stakeholders.
As the technical partner behind Eco Choice Aotearoa, we assess environmental performance against robust criteria. We apply this rigour to sustainable procurement, verification and audit support, helping clients turn sustainability commitments into requirements they can implement and check.
Through our participation in the Inogen Alliance, we support organisations requiring consistent environmental, health and safety auditing and assurance across multiple jurisdictions.
By leveraging our international connections, we offer:
- Access to global auditing expertise and specialist technical capability
- Insight into emerging international regulatory and industry trends influencing local markets
- Independent audits informed by recognised global best practice and ISO-aligned frameworks
- Coordinated audit programmes for organisations operating across multiple jurisdictions
- Alignment and verification of EHS systems and controls against applicable legislation and recognised international standards
Through the Inogen Alliance and broader global networks, we remain connected to evolving regulatory expectations and international auditing practices. Our clients benefit from strong local knowledge supported by recognised global expertise.
