Our Team

Our insurance underwriting team is made up of passionate people who have decades of experience and knowledge within the charity, care, faith and education sectors. We provide a quality service with competitive premiums, because we want you to be providing for your community.

David Leather 
David Leather is Concordia’s CEO, and with 45 years of experience in the insurance industry, he knows exactly what people need when they are looking for comprehensive insurance within community organisations.
David has a wealth of knowledge when it comes to the needs of these organisations. With this in mind along with the joint venture partners of All Churches Insurance Bureau and A&M, he set out to create New Zealand’s only specific insurance provider for the faith education, charity, and care sectors.
David has a well established reputation within the industry, especially in these niche markets, which is why Lloyds of London support Concordia with substantial underwriting capacity. Additionally, his experience working with community and church organisations following the Christchurch earthquakes gives him unique insights into helping organisations when the worst happens.
