ANZ Group Holdings (ASX:ANZ, NZE:ANZ) is making targeted assistance available for business and farming customers, subject to approval, as they seek to recover from recent storms in Southland and South Otago, New Zealand, according to a Wednesday statement.

The lender's staff is "out in the community and on the road, talking to business owners and visiting farmers in some of the worst-affected areas to get a better idea of the extent of the damage," Lorraine Mapu, ANZ Managing Director of Business and Agri, said.

The measures include temporary overdraft facilities, the ability to defer loan repayments, or moving to interest-only.

Agricultural customers can also access the bank's low-interest Business Regrowth loan. Eligible customers can borrow up to AU$300,000 at a special fixed rate of 3.49% per annum for three years.

The bank's shares fell a little over 1% in recent trading on the New Zealand bourse on Wednesday.
