White says some people have questioned why the council is not using NZ Post, which they are more familiar with.
The council has worked with DX Mail for the past seven years to successfully deliver rates notices. White says there is a cost-saving benefit and DX Mail also clear the boxes daily.
"This means votes can be counted right up until the last day as DX Mail are committed to clearing all boxes at midday on 17 February. NZ Post does not offer this service," White says.
"This is fantastic because in the past people had to bring their votes into council on the last day if they wanted it to be counted. Now people can post in their community right up until the morning of February 17."
A page on the council's website, pncc.govt.nz/vote, has a map and details of locations of all DX mailboxes and temporary ballot box stations.
"If people place their voting papers in a NZ Post box, they will be forwarded to DX Mail, but there is more surety of their vote being counted if they place their vote in the correct place within the voting period," White says.
If you have not received voting papers, email elections@pncc.govt.nz, ring 06 356 8199, or call into the council's customer service centre.
Voting closes at noon on Wednesday, February 17. The outcome is expected to be announced on February 22 on the council's website and social media sites. The new councillor will take up their role immediately.
