Opposition parties are calling on everyone to watch a "sickening" documentary on child poverty in New Zealand, due to be screened on tomorrow night.
Labour's deputy leader, Annette King, says it reveals the truth and the government will no longer be able to pretend there is not a problem.
The Mana Party's co-vice president, John Minto, is issuing the same call and says it shows the reality of what 27 years of free market policies have delivered.
The investigation says up to 150 babies who died in New Zealand last year might well be alive if they had been born in Sweden, Japan or even the Czech Republic.
Filmmaker Bryan Bruce explores almost 100 years of child welfare in New Zealand and reveals how child heath has deteriorated in recent years.
It follows a report which found 200,000 New Zealand children live in poverty, more than half of them Maori or Pacific Island.
Ms King says it reveals the "sickening truth" about child poverty and it's going to be a wake-up call for every member of the government.
"The prime minister has been in denial about this country's poverty problem for years," she said on Monday.
"He has shunned numerous attempts to address the issue through a cross-party approach and dismissed the concerns of experts working in the field as `rubbish'."
Ms King says last year more than 25,000 children were admitted to hospital with respiratory infections while cases of meningitis and rheumatic fever - diseases usually associated with third world countries - are at unprecedented levels.
The documentary, Inside New Zealand: Inside Child Poverty is to be screened on TV3 at 7.30pm on Tuesday.
