The NZ Rugby Union was among those who spoke out against the 80 per cent proposal - its chief Steve Tew had told the select committee it would force some clubs to fold altogether and others would have to increase fees by up to 500 per cent.
Labour's spokesman Trevor Mallard said National had effectively hi-jacked the bill to push through its own aims and Mr Flavell should withdraw it altogether.
He said replacing Mr Flavell's provision for councils to reduce and eliminate pokies in some areas by allowing those operators to simply move elsewhere while retaining the same number of pokie machines would only increase gambling.
National's changes mean that instead of requiring 80 per cent of pokie profits to go back into the community, the Government will be able to set an unspecified minimum percentage by way of regulation instead. National also baulked at a provision allowing local councils to reduce or completely ban pokies in areas where disadvantage and problem gambling were major issues. Instead, National will allow operators to move their machines to another venue.
National also rejected Mr Flavell's provision to exclude horse racing from receiving pokies funding and for local authorities to distribute pokies grants instead of gaming trusts.
Problem Gaming Foundation chief executive Graeme Ramsey said the amendments to the bill meant it was effectively now mis-named because it would have little, if any, effect on problem gambling.
"I think what we are seeing is a proposed radical rewrite of the bill, and I don't think it will do a great deal for harm minimisation at all."
Internal Affairs Minister Chris Tremain said the changes were common sense and would allow for those operators to move from low socioeconomic areas to areas such as the CBD where the prospect of harm was lower.
