Act Party leader David Seymour is rejecting claims he has been on a spending spree buying up thousands of followers to bolster his official Instagram account.
Since Wednesday Seymour's account, which trumpets Act policy and political engagements, has ballooned from 23,800 to 73,900 followers.
At one point 100 followers joined the minor party leader's account in less than a minute and a further 2000 followers were added in 20 minutes.
The sudden surge of followers has raised suspicion the Epsom MP or those connected to the Act Party have been paying for followers to boost the modest following.
