Online voting on its own won’t be sufficient to mobilise those who are under-represented in voting, but it is necessary to modernise elections if we want to increase participation in our democratic processes. 
A Massey University survey shows that young people are more likely to vote if it is made more convenient. The research is based on a survey, which showsonlinevoting is more of an incentive than a $50 payment. The survey, which was conducted by academics and students from the university's politics programme, targeted 18- to 24-year-old students to gauge their attitudes to the general election. Of the respondents who indicated they did not intend to vote, 75% said they would be more likely to vote if onlinevoting was introduced, while only 51% said they would be motivated by a $50 payment. 
In NZ, we have seen good examples of increased digital participation with the census, where 35% of forms were completed online in 2013, which is up from 7% in 2006. 
Online voting will also make it easier for people with disabilities and other physical barriers for accessibility to vote.
