A snap poll has found 30 percent of New Zealanders support the protest on Parliament's lawn.
A poll of 525 people released by Horizon this morning, shows 61 percent oppose the convoy, which is still blocking roads and growing in numbers 11 days into the occupation.
Nine percent of those surveyed didn't have an opinion or didn't know.
The poll also found 28 percent of people oppose the current vaccine mandates - slightly lower than the support for the protest - while 64 percent are in favour of them.
People aged between 34 and 44 were the largest group opposed to mandates.
People aged over 75 are the most likely to support the mandates.
