"The sporting clubs are are still eligible to get money, that's not going to change. The bottom line is someone will still make a decision about that money.
"The key part around that is who is it going to be? Is it the trusts that we have at the moment, some which have been found to be rorting the system?"
The Gambling Amendment bill would gradually replace "pokie trusts" with more transparent local authorities.
Submitters, including some councils, have opposed this change because it would create more costs for territorial authorities and open the process up to political interference.
Mr Flavell said he had heard this concern and was open to suggestions from the committee.
But in his presentation he emphasised the problem of corruption among pokie trusts.
He cited a Department of Internal Affairs report from this year which showed 750 trusts had not been able to explain their high costs.
Mr Flavell said it was not possible to eliminate pokies or gambling from New Zealand, but it was possible to make the distribution of funds fairer.
The committee received nearly 5000 submissions on the bill, the majority of which came from sports clubs and community groups concerned about losing their funding.
