The Federal oppositions Indigenous Affairs spokesman, Nigel Scullion says the Northern Territory and Federal Governments have reneged on a promise to properly refurbish remote Indigenous housing.

The Territory Government has admitted the budget available for every refurbishment under the Strategic Indigenous Housing and Infrastructure Program, or SIHIP, will not be enough to bring all the houses up to legal standards.

It will use its own housing maintenance program to fill in the shortfalls.

Senator Scullion says the refurbishments do not meet expectations.
