"Queenstown is very transient and people seem to change their address often, which means we lose track of them if they do not complete a redirection form with the PostShop," Ms Skelt said. "If they move out of the electorate it does mean they have to re-enrol after one month in the new electorate. I think a lot of young people do not realise this."
Almost 50% of 25-29 year olds in the district have yet to register. Nationally, the figure is 20.63%.
The district also trails the national figures in the 35-39 age group (by 20%), 18-24 (22%) and 30-34 brackets (30%).
Ms Skelt said there was a "lack of interest" among voters, and youth in particular, and that many thought about enrolling only two to three weeks from the election.
"As with all potential electors across all ages, there will always be people not interested and they will be hard to engage, but my motto is one does make a difference, but it takes many to make a change."
The electoral enrolment office has sent representatives to areas with the lowest enrolment figures to "hit the pavement and door knock" in a bid to reverse those statistics.
Jen Jolley has been employed in Queenstown since the beginning of August to approach homes and businesses in the area to encourage people to enrol.
"We're going to be out and about for the next eight weeks before the election, to help everyone in our community get the information they need.
"This year is really important. As well as voting for the people and parties you want to represent you in parliament, you're voting on the way you will make those choices in the future.
"If people move house and don't update their address details and we get enrolment information sent to them returned to us as undeliverable, then we have to remove them from the electoral roll.
"Being out in the community gives us the chance to remind people to check their details, and help them re-enrol if they need to."
