The Maori Party's Dr Pita Sharples is speaking next, and he says the Budget goes some way to addressing inequalities in New Zealand.
"We know that mass immigration is being used to prop up consumer demand on our economy. Most of these new arrivals are going to Auckland."
"Employers will be delighted with the news that ACC levies are to come down.
"The extra investment going into skills and employment carry the right messages.
"Though the increased investment in research and science is pleasing will still not be enough to bring us up to OECD measures.
"Stronger forecast tax revenues has given the Government a bit more room to move in terms of additional new spending to the tune of $5.1bn over the four year forecast period."
"Our first reaction to this Budget was to call the Serious Fraud Office," he said.
"This is financial deceit on a grand scale."
The reality is cashing up of losses is just another form of government grant, he said.
"Either way, it is good news for start-ups."
Meanwhile, Bill Rosenberg, Council of Trade Unions economist, said the Budget fails to address a crisis in jobs, low wages, increasing poverty and inequality that New Zealand currently faces.
"These problems have grown over the last five years, and this Budget doesn't do enough to help solve them.
"The Budget should have been about more assistance for people who lose their jobs, productive community work programmes, and a strategy to help manufacturing and other higher value, higher wage industries grow."
"This government is stripping money away from students, both directly through their loans, allowances, and higher fees, and indirectly by attacking the quality of their education."
"Instead it is subsidising $29 million to private education companies to help them make a profit rather than investing in local communities' public education institutions."
He said the rising costs which would come as a consequence of revising the rebuild costs, and therefore lengthening the rebuild period, may make it difficult for many business cases to stack up.
Greens co-leader Dr Russel Norman said it was an "angry" speech for a Prime Minister to deliver on Budget Day.
"The global clean energy market is booming. But New Zealand's chance to use the innovation and expertise that is fostered in Meridian, and pocket the billions of dollars on offer in this worldwide industry, has just been kicked into touch," he said.
"This is not a budget for New Zealanders. This is not a Budget backing our Kiwi innovation and expertise. And it's not a Budget for our long-term prosperity."
"The finance minister should have added the words 'slowly' and 'cautiously'," Armstong said.
"We've had enough of game shows, and the 'Wheel of Misfortune'."
Mr Shearer went on to offer a suggestion to Mr Key, in the form of a quote a disgraced National list MP used this week while announcing his resignation: "Lead, follow, or get out of the way."
"You've had your chance. Follow Aaron Gilmore, and get out of the way," Mr Shearer said.
"I will lead a Government that puts people first."
"That was truly awful," Mr Key - who held up Bill English as "the envy of the Western world" - said in response.
"It was like watching MySky at half speed."
Mr Shearer has questioned why the Government won't heed recommendations for an MMP review if it's not to protect partners John Banks (Act) and Peter Dunne.
Mr Shearer likened United Future's Peter Dunne to a contestant on Survivor: "Sometimes he outplays, he never outwits, and somehow he outlasts."
"They deserve a Government that is better than this," Mr Shearer said.
"This has always been a Government for vested interests. For casino giants, movie makers ... and National Party no-hopers."
Bill English said the total estimated cost of earthquake damage in Christchurch has been increased by $10 billion, and is now $40 billion.
"Budget 2013 confirms $2.1 billion of additional government funding to the earthquake recovery, including $900 million of new capital from the Future Investment Fund. This will take the Government's total share of the rebuild to around $15 billion," he said."
Deloitte's Managing Partner in Christchurch says the Government is doing a "world-class" job of an "extremely complex and costly disaster recovery process."
Brett Chambers said: "Today's announcement will benefit not only the people of Christchurch, but the whole of New Zealand, as the country depends on the full economic contribution from its second largest city."
The Government's social housing measures include a stated record $2.9 billion investment by Housing New Zealand over three years, and a bill which aims to enable the Government to work urgently with councils on streamlining resource consents for new housing developments in areas of poor housing affordability.
In response, Nathan Argent, Greenpeace's chief policy advisor, said:
"The half-baked decision to sell clean energy gem Meridian could lose the economy billions of dollars.
"The cash generated by selling this company will look like peanuts compared to the huge rewards on offer if the Government actually backed our clean energy expertise, rather than flogging it."
Mr English said the Mighty River Power offer demonstrated that the Government's share offer programme was effective.
"It raised $1.7 billion, which will be used to invest in hospitals, schools and other assets our communities want and need.
"At the same time, 113,000 New Zealanders took the opportunity to invest in a strong local enterprise.
"Meridian will benefit from that same process, and New Zealanders will once again have the opportunity to invest in the Initial Public Offering of a large New Zealand company."
Mr English says there are four main priorities for the Government:
* Managing Government finances responsibly.
* Fostering a more productive economy.
* Delivering better public services.
* Rebuilding Christchurch.
"New Zealanders can look to the future with well-earned confidence and optimism," he said.
He begins by outlining the state of the New Zealand economy at the time of the current National Goverment's first Budget in 2009, after the global financial crisis of 2008.
"The Government's plan has not involved radical change. That plan is working as international bodies like the IMF has recognised. The NZ economy grew by 3 per cent last year.
"Although unemployment is too high, attracting investment which creates jobs is a focus for the Government.
"We are on track to post a surplus in 2014-15. Budget 2013 is about building momentum."
After two budgets of zero new spending, Bill English has budgeted $800 million for new spending in the next financial year which will still end up in deficit - $2 billion at the last forecast. (Read more: Budget: English to ease purse strings)
