"While we were at the bank we saw a gradual tightening of credit conditions in New Zealand," Pryde told the Herald.
"The largest banks in New Zealand were not necessarily pulling back from providing credit, but certainly were becoming more conscious of where they deployed capital and the return that they got on that capital, which made it harder for New Zealand's businesses to access credit," he said.
"We believed that we could better serve New Zealand businesses by partnering with them to assist in procurement of debt facilities from the outside to allow them to grow and prosper," Pryde said.
A number of new entrants had come to the capital markets - alternative lenders, non-bank lenders, family offices, high net worth individuals - all of which had shown an interest in supporting New Zealand businesses.
Very low interest rates had seen more private credit come into the funding mix.
"When we floated the idea to Brendan he liked the idea of a service that could help New Zealand businesses grow," Pryde said.
Pryde Capital's formation comes against a backdrop of increased complexity and regulation in New Zealand's debt capital markets.
New Zealand's traditional banks continue to simplify their business models to a more standardised and digitised offering, corporate New Zealand businesses are finding it harder to access credit to support and pursue their business ambitions, Pryde said.
Pryde said the firm would provide "non-conflicted" debt advice to New Zealand businesses.
