The timeframe for the seismic strengthening of Kowhai Park's castle has been extended.
Strengthening work began on March 21 and was originally expected to take six weeks to complete.
However, work is now expected to be completed in early May.
A Whanganui District Council spokesperson said the extra time was required to remove additional mass concrete, which was used as foundational material and discovered during the demolition process.
The spokesperson said there had been a delay in some materials due to Covid-19 affecting supply lines and causing staff shortages, which the council expected for the project previously.
