The main issues, he said, revolved around loss of business and damage to residential property.
"For businesses this has included things such as lost bookings or opportunities. For residential properties the main issue is damage to plumbing from the diesel contamination."
Mr Till noted that the council has been asking people when making an insurance or compensation claim to send a copy of the details to the council so that it could develop a better picture of the damage and losses overall.
"This information will be invaluable for council when making further deliberations on what type of additional assistance Raetihi may need," he said.
"It will also be very important to have an accurate understanding of Raetihi losses in any discussions with RAL or central government about any future assistance.
"The picture so far is that individual losses are averaging between the $1000 to $4000 range with the higher end being suffered by local businesses."
Mr Till added that the council would still like to receive copies or a summary of individual claims.
"We are not interested in individual personal details but developing a 'big picture' view of total losses."
People can either post the information to the council or to info@ruapehudc.govt.nz with 'Diesel Contamination Claim' in the subject line.
