The sign was put up before Christmas but at its January meeting, Mataura Community Board members expressed concern the lettering on the sign did not "pop".
The sign was different from the concept plan agreed on by the former board.
Sarah Crispin, of Crispin Design, made several changes because of material issues including the colour of the pebbles and a darker colour for the concrete plinth.
Shortly after the meeting, it was discovered the embedded resin river motif had cracked and delaminated.
In a report to last week’s board meeting, Gore District Council roading assets manager Murray Hasler updated members on progress with the signs.
The sign intended for the northern approach had not been put up and was transported back to the Mosgiel factory of fibrous plaster company Seddon’s for repairs to the resin river motif.
The southern sign had already been put up before the defects were noticed.
Repair of the motif on this sign will be carried out on site at the same time as installation of the northern sign.
Seddon’s will begin its repair of the sign at its factory over the next few weeks.
This will enable staff to refine the method of repair which they will repeat on the sign already installed.
The next step would be to choose the best colour for the lettering so the letters stand out, Mr Hasler said.
During the discussion, members considered new concept plans by Ms Crispin.
They demonstrated the effects of different colours on the impact of the sign.
Most members preferred kowhai park as the new colour for the lettering.
Councillor Neville Phillips said he had already discussed with Mr Hasler the possibility of attaching coloured vinyl letters to the sign.
"It’s so easy to rip off the vinyl and put another colour on if you have to."
It would be less expensive than painting the sign and once it was known which colour stood out the sign could be painted permanently in that colour, Cr Phillips said.
Chairwoman Nicky Coats asked if the second sign would be painted once it was put up.
Cr Phillips said it would be.
