Two protesters have been arrested outside the central Auckland venue where Prime Minister John Key has been delivering a post-Budget speech.
Around 30 people who said they were angry at the announcements in the Budget gathered outside the Langham Hotel on Friday.
Radio New Zealand's reporter at the scene said about 20 police officers formed a barrier at the hotel entrance.
Mr Key's speech was not delayed.
Earlier, about 30 protesters tried to disrupt a post-Budget National Party conference in Auckland.
The group chanted loudly and shouted abuse at MPs as they arrived at the meeting in Mt Wellington.
The protesters were led by ex-MP and former Mana Party candidate Sue Bradford and the group included representatives from the Auckland Action Against Poverty group and the Service and Food Workers Union.
They stood at the entrance of the conference centre waving banners waiting for the Prime Minister to turn up, but eventually left before Mr Key arrived.
About 15 police officers were called to the scene after a minor confrontation with some of the protesters resulted in one being knocked to the ground.
