A $520,000 gap between income and operating costs will see Horowhenua ratepayers financially supporting the new Foxton museum, gallery and community centre complex after it opens on November 18.
Latest figures from Horowhenua District Council show the Te Awahou Nieuwe Stroom development will have annual income of $133,000 and operating costs of $651,000.
HDC has said the operating costs are budgeted in its annual plan.
HDC chief executive David Clapperton said the figures were in line with HDC's funding policy for libraries and community centres, with operational costs having a targeted rate of 75-85 per cent and fees and charges making up 15-25 per cent.
"The Te Awahou Nieuwe Stroom budget is to ensure that this amazing community facility, which will be a major visitor destination, is [part of] the social infrastructure and a community gathering space for residents and visitors," Mr Clapperton said.
