Gold 150 and Arrowtown 150 co-ordinator Julie Hughes, of Arrowtown, said the six-month celebrations programme was growing all the time, with an even bigger line-up for the second half of the year.
"The next six months are huge and all up we have $430,000 of events planned for the celebrations planned thanks to funding from the Central Lakes Trust," Mrs Hughes said.
Highlights included the "Dusty Trails to Cromwell" Cavalcade, which will see about 550 people descending on Cromwell from all directions by foot, bike and wagons from February 18.
On February 25, the costume-clad revellers will make it to their destination for a family fun day and "huge hoe-down" to celebrate their journey.
Also looming large are the Nevis Gold 150 celebrations, starting on March 9 in the Nevis Valley, which includes gold-panning, blacksmith demonstrations and a replica of the old post office.
"It's an amazing place in there and perfect timing to go in," Mrs Hughes said.
