Shadow treasurer Chris Bowen will pave the way for more policies targeting the wealthy and possibly paring back legislated company tax cuts in a speech in which he will badge Labor's approach as "Hawke-Keating refurbished".

In a scene-setting address to Per Capita to be delivered today, Mr Bowen says Labor will build on its announced plans to curb negative gearing, halve capital gains tax exemptions for investors, increase the top rate of income tax, and change the tax treatment of trusts.
