Students had used a long rope to ring the bell when it sat atop the school building, although students today ring it an arm's length away at ground level and must wear ear muffs to dull the peal.
Mrs Feringa said wooden sections of the bell tower were rotting and the weather vane had ceased working despite being at some time refitted with aluminium letters at each of the compass points - the E for east though had been lost.
"We'd got our kaitiaki group of students, who painted murals around the bell tower base last year, to have a look at it as part of a project. But they realised the tower needed professional repairs and so we're making a call to former students, professionals and our community to help us out," she said.
"We're now getting to the point of wondering whether the thing will collapse when a student is ringing it.
"We really need help to renovate it and replace whatever needs to be replaced.
"It's out of our financial range and professional skill set to do it ourselves and we need anyone out there who can come forward to support us and help make our bell tower safe and whole again."
Anybody who can help with the revamp of the bell tower may call Sara Feringa at Masterton Primary School on 06 377 5297.
