A concert was also in the pipeline although who was playing and at what venue were yet to be confirmed.
Mr Blas was involved in the construction of skate parks in towns and cities including Hawera, Oakura and Papakura. He also designed the Barry Curtis skate park in Manukau and Victoria Park skate park in Auckland.
"There wouldn't be a skater out there today who hasn't skated one of his [Mr Blas'] parks," Mr Balderston said.
A Facebook page promoting the event, called Skate for Blas, was started yesterday and already had more than 400 members and many offers of support.
Mr Blas has been living in Christchurch with partner Selena Ounsworth and their three children Ethan, 7, Mia, 5, and Arnica, 4, since moving there last year to work as a foreman in a construction company helping with the Christchurch rebuild. Mr Blas' sister Sarah Green said family were keeping vigil by his bedside and support and well wishes had been pouring in from around the country.
He had suffered several setbacks including a stroke and coughing but he kept fighting back and was responding to family being in the room. So far about $2500 had been raised through www.givealittle.co.nz/cause/JamesBlas and a special bank account under Mr Blas' name had been set up at ANZ Bank with the number 0605 6500 544 3611.
"Everyone's hoping for the best but it's likely to be a long time before he recovers," Mrs Green said.
