Chris Bishop has called out the "disrespect" shown to the National Party and its volunteers after a number of hoardings were vandalised over the weekend.
In a tweet on Saturday night, the Hutt South MP shared photos of the destruction to multiple campaign hoardings.
"Someone really doesn't like our plan to four-lane the roads between Auckland, Whangarei, Hamilton and Tauranga and complete Auckland's Rapid Transit Network," he jokingly captioned the post.
Bishop - who currently holds the infrastructure and transport portfolios for National - said a couple of hoardings were "demolished".
"Unfortunately they've been hit to varying degrees. Two of them have been completely tipped over and smashed up. A couple of others have been pretty demolished. They'll take a bit of repair work," he told Newshub.
"It's just disappointing to have this happen. They've been up for 24 hours basically, and already someone has gone and shown disrespect for the volunteer's time, who got up at midnight the night before to put them up."
Although the hoardings are relatively inexpensive to produce, Bishop said it's not about the financial cost.
"It's not so much about the cost... it's the time for volunteers. People spend hours erecting these things, getting them prepared. We had a team of 30 people putting them up around the Hutt at midnight the night before," he said.
"To see them come down straight away is just pretty disappointing. At the end of the day, they are the property of me and the National Party. It just shows a real disrespect for that.
"It's very disappointing and hopefully we don't see too much more of it."
Newly-elected Opposition leader Judith Collins boosted Bishop up the caucus rankings to number seven as part of her Cabinet reshuffle on Thursday, also promoting the MP to Shadow Leader of the House.
The vandalism follows a stoush between the Labour Party and New Conservatives over signs in Auckland's New Lynn, and swastikas appearing on New Conservative signs in nearby Avondale.
