The Law Society says people do not have enough time to understand the Canterbury earthquake recovery legislation before it becomes law.
The bill is being considered by Parliament under urgency.
It passed its first reading on Tuesday, and went through a truncated select committee process on Wednesday in Christchurch and in Wellington.
Law Society spokesperson Rachel Dunningham says people will be shocked by the bill's provisions limiting the compensation the Earthquake Recovery Authority has to pay for removing rights and property.
"When you look at the detail there are all sorts of things compensation is not paid for," she says.
She cites as an example the removal of a resource consent or existing use right - which she says are valuable rights.
