The company has built its business through word of mouth and targets middle-income earners with the aim of providing a plan to reduce debt levels.
It brokers home lending with both Kiwibank and Sovereign and also sells insurance.
Despite competitive conditions Collins said its lending was up 40 per cent on last year and it was at present pulling in about a third of Kiwibank's new home lending.
The company specialises in refinancing existing loans although about a third of its business was also first-home buyers.
Collins believed its focus on helping clients to reduce debt was proving attractive in the present climate.
"The Government's rhetoric and a focus on debt has driven the public to focus on this."
Collins said the message to reduce debt was also getting through as the company had noticed a significant reduction in people wanting to increase their mortgage debt to buy a car or pay for a holiday.
"Our top-ups are 50 per cent down on the year before."
