The re-opening of the Whanganui Regional Museum at Queen's Park has been pushed back three months.
The Queen's Park building has been undergoing refurbishment and seismic strengthening for about two years but it was recently announced it would be open to the public again next month.
But director Frank Stark announced yesterday that had been postponed until mid-March.
Stark said "resource issues" and problems finalising some of the installation work during the Christmas period had caused the two-month delay.
Some of the problems had been compounded by the museum's need to rely on suppliers and contractors from outside Whanganui.
