Mr Seymour spoke alongside other Act MPs at the King’s and Queen’s Performing Arts Centre in Dunedin on Saturday as part of the party’s Honest Conversations Tour.
About 100 people attended the event.
Parliament was in recess for three weeks, which gave Act MPs the opportunity discuss policy and hear the concerns of those who felt unheard at times, Mr Seymour said.
"Wellington can be so consuming that you can take your eye off what people are really talking about in the rest of New Zealand."
MPs would speak at 45 locations throughout the tour.
Each would have new a policy to be discussed alongside the issue, he said.
"We’re not just criticising the Government, although we think there’s a lot that deserves to be criticised," he said.
"We’re also proposing how New Zealand could be better for the people that pay the bills."
Mr Seymour said he had no confidence the group4 Covid-19 vaccine rollout would be delivered by the planned dates.
"The Government needs to stop pretending it’s the best in the world and everything is perfect."
Something had "clearly" gone wrong with the contracting of the vaccine delivery, he said.
He had no idea what the issue was, but said the Government should be open about it.
He hoped the Government could do a good job with the vaccination programme, but believed jabs would be going on into next year.
A recent poll showed Mr Seymour ahead of National Party leader Judith Collins in the preferred prime minister stakes and Act at 11% of the popular vote.
The election was wide open and there was still space for more growth, Mr Seymour said.
"It’s not like a sports tournament where you peak too early, it’s just about proposing a better way forward and behaving well."
