The Dunedin City Council will spend $41,000 on the work.
A small team of specialists will strengthen the monument and replace some of its ornamental finials.
Other finials will be repaired, as will water damage to the structure's terrace and lower chambers.
Corroded steel crimps will be removed.
The work is expected to take up to six months.
Council parks and reserves team leader Martin Thompson said the safety work would probably be followed by a more extensive restoration within the next three years, although that was yet to be priced and would need approval as part of next year's annual plan process.
