"There has been a slow start across the country, but it will get there," Mr Lampp said.
"I just encourage people to pop their papers back in the post as soon as possible so we get them with plenty of time to spare."
He said the last day to post voting forms would be next Wednesday, otherwise voters would have to drop them off at the Rotorua Lakes Council offices before midday on Saturday, October 8.
The council's deputy electoral officer for Rotorua, Rick Dunn, said he was confident of achieving a better turnout than in 2013.
"The trend we are seeing in Rotorua with regard to voting paper returns is similar to what's happening around the country.
"Given what appears to be a higher than normal level of local interest in council and the elections - going on media coverage and social media engagement on election-related matters - we still anticipate a better voter turnout this year than in 2013."
He said people appeared to be more interested in council matters and hoped that would translate into more people having their say.
"We also anticipate a greater turnout of Maori voters as a result of the higher profile of council prompted by the Te Arawa partnership, the higher number of Maori candidates standing for council and given Te Arawa has endorsed several of those candidates."
Former Rotorua mayor Grahame Hall said he was surprised by the low turnout so far and was not confident of a higher turnout than in 2013.
"But it's not too late. I would encourage everyone to get out there and exercise their democratic right.
"Local government is really important and every single vote counts. But I'm very surprised that with the amount of publicity there would have been a hell of a lot more interest."
The council is also part of Local Government New Zealand's "Vote 2016" campaign aimed at getting a voter turnout of 50 per cent or more.
As part of the Vote 2016 campaign this Saturday has being declared "Vote Day".
Local Government New Zealand chief executive Malcolm Alexander said some regions' voting numbers were up and some were down, but were, in general, tracking as they were in 2013.
"One stand out is Auckland, which is ahead of 2013, and that's encouraging.
"But we have to be careful not to generalise.
"Our goal this year is 50 per cent from a national average point of view and we think that's an achievable number.
"You need to exercise your right to vote, if you don't you have lost your right to criticise if you didn't feel it was important enough to vote in the first place."
