Finance Minister Sammy Wilson has said the Republic's bad bank Nama is making "significant" finance available to its debtors here.
Mr Wilson spoke following a meeting with Frank Daly, the chairman of the body set up to cleanse the Irish banking system of toxic loans on property.
Nama, which has acquired loans of £3.35bn on Northern Ireland assets, is able to advance funding to debtors for the development or improvement of assets, subject to conditions.
A recent report from the Republic's Comptroller and Auditor General said it had made just £24m worth of property sales in Northern Ireland - just 1% of its sales to date.
The minister said: "I was pleased that Nama is making significant finance available both in the form of lending to Northern Ireland debtors for the development of existing sites and in terms of vendor finance for potential buyers of commercial property."
