The changes will be done as part of a wider overhaul of broadcasting laws. It would also consider recommendations for more flexible use by parties of their broadcasting allocations.
Adams also expected to change the law before 2017 to cater for the increasing trend of advance voting in 2014 and the Northland byelection after that.
That would result in a ban on election campaigning or campaign advertising around advance voting booths, as well as providing more booths and allowing votes to be counted earlier.
In 2014, 29 per cent of voters (717,579) voted early - much higher than in 2011.
Although campaigning is banned on election day itself, there are no restrictions for advance voting and the Electoral Commission has relied on the good will of the candidates not to campaign outside them.
Several candidates, including then Labour leader David Cunliffe, voted early and urged their supporters to do the same.
Adams said the Government would work on those as well as proposals to boost voter turn out with the Electoral Commission.
