The other new category is the Novice 3D award for first-time entrants.
"The aim is to attract entries from young artists although it is open to anyone who has not entered before," Charlton said.
"It can be problematic if we get a lot of large 3D entries and I know they have not been encouraged in the past.
"I don't know if it's stupidity or bloody mindedness on my part but I like to encourage inventiveness."
There are 17 categories in the awards - 10 visual arts categories, five photography categories, and two general categories for best in Ruapehu as well as the people's choice award.
Charlton said the generosity of sponsors means that a total of $7500 in prize money will be offered this year and the top prize is $2000 for the premier award.
The 2017 premier winner was Ray Woodhouse for his 3D work Light Flight.
Registrations for the 2018 awards close on Friday, June 15 at 5pm and posted entries must be received by 6pm on June 22.
"Entrants can deliver their work to Raetihi Information Centre until 6pm on June 24," Charlton said.
"We have made it easier for people to download the entry forms online this year and we have 60 entries so far."
Charlton said there is always a last-minute rush for people to submit their entries and she is expecting 2018 to be no different.
Winners will be announced on July 3 and all entries will be exhibited at Raetihi's Royal Theatre from July 4-14.
