Gateway Credit Union has expanded its third-party distribution network, after forming a partnership with the aggregator Connective.Gateway has been working with Yellow Brick Road since 2009 and with Mortgage Choice since 2011. Connective has 1800 brokers and describes itself as the fastest-growing mortgage distribution business in the market.Gateway's chief executive, Paul Thomas, said the credit union had made a substantial investment in its systems to ensure the consistent delivery of a high quality service to its distribution partners. Thomas said: "The system is largely automated. Loan applications do not have to be re-keyed and approvals go through a decision support system."Soon we will be generating documents and sending them out as PDF files."If you make it easy for your partner to do business, then, all things being equal, you will get more business. Not many mutuals have this level of sophistication in their systems."Thomas said Gateway's relationship with Yellow Brick Road had not been affected by YBR's move to align itself closely with Macquarie Bank.
