The Earthquake Services teams have 20 assessments to make, but Mr Staples said there would be more later.
The June rain caused slips that made some houses unable to be occupied. Payments offered by EQC have not been enough to see some owners back into them.
About 30 affected Whanganui people attended a meeting with Mr Staples in November. He outlined the way EQC and insurance companies work.
When land is affected EQC will pay for either the repairs or the value of the affected land itself, whichever is cheaper. Where houses are affected, it will pay the first $100,000 for repair, with insurance companies paying the rest.
After that meeting "quite a number" of affected people made inquiries about getting his company's help to get a better outcome from EQC.
Mr Staples' usual charge is 20 per cent of what they get from EQC, over and above their initial offer. He's offered Whanganui people a lower percentage price.
Mr Staples said increasing those payouts can involve a long court process, and the cases will have to be taken individually, because they are all different.
Meantime, his company is still busy trying to wring the correct entitlement from EQC for Christchurch people.
