In August last year, NRC said it was considering lending Northland Emergency Services Trust (Nest) $9.8m using access to better interest rates through LGFA.
Such an arrangement will save Nest about $200,000 a year in interest repayments. The proposed loan will have no impact on rates.
Mr Shepherd said there were obvious benefits of obtaining cheaper loans.
"A capital sum has to be put up front at present to get work done. In the past, we have used council reserves or money from commercial enterprises like banks, which get returns of seven to eight per cent on those loans.
"With LGFA, the returns are only four per cent and so the community will benefit through a reduction in targeted rates," he said.
Mr Shepherd said since NRC did not do a lot of borrowing in the past, it did not join LGFA, but its work has now expanded.
In its long-term plan, NRC is proposing all ratepayers in the region chip in financially for flood remedial work rather than those who directly benefit from it.
If the proposal gets the green light, an average ratepayer will fork out about $67 annually, or $1.30 more a week.
