"Once we have this information we'll be able to give an update on timing," Mr Walker said.
Back in March, 2010, there was a stoush between the district council and NZTA when the agency put up new 50km/h speed signs with the new spelling on Great North Rd near the intersection with Montgomery Rd.
But no sooner had the signs gone up the then mayor Michael Laws ordered their removal.
A vocal opponent of changing the spelling, Mr Laws said the signs were "both illegal and misrepresented our city's name".
He said the two spellings were to be gazetted later that year but nothing should change until Parliament passed the new spelling.
In 2009 then NZTA area manager Errol Christiansen told the Chronicle the agency would change the road signs as and when they needed replacing, but it would not be a process that would happen all at once.
