Taxpayers Union economist Mac McKenna said Labour had been the most ambitious, with expensive new packages aimed at each of the major cities.
The National and Green Parties had made smaller promises.
In the last week, Labour announced $300million for a Christchurch capital acceleration fund, $100million for transport in Christchurch, $30million for the Auckland Skypath, $22million for a new rail line between Upper Hutt and Trentham and a renewal of the $100million Urban Cycleways Fund.
Labour had also committed to building a new Dunedin Hospital, he said.
"However, unlike National’s proposal, they will not make use of public-private partnerships. Labour claims their hospital will cost the same as National’s — about $1.4billion over seven years."
The Bribe-O-Meter had taken Labour costings as being accurate, although they were questionable, given the historic efficiency advantages public-private partnerships had over government builds, Mr McKenna said.
The total cost of those targeted packages was more than $1billion over the next three years.
Labour’s total new spending in the next term was now $20.4billion, behind only New Zealand First, at $26million.
Labour’s spending amounted to $11,828 per household, compared with $15,062 by NZ First.
The Green Party had increased its total new spending promises to $9billion. Major announcements last week were regional transport policies and new environmental spending funded by a plastic bag levy.
National had increased education spending by $290million over three years and promised $120million for a Christchurch sports stadium. Smaller spending included $500,000 for winter Olympians and $150,000 to stimulate demand in geothermal energy.
• The latest costings did not include policy announcements from yesterday.
