A claim tightening the Proceeds of Crime Act isn't the right way to deal with gangs

It's understood the Government will announce a law change which will make it easier for police to seize gang assets held under associate's names.

The law will also make it harder for criminals to shelter money with Kiwisaver.

National Party Police spokesperson Mark Mitchell says while it's good to go after assets, it misses the bigger issue.

He says it will do nothing to lessen gang and gun violence.
