These deaths could be prevented if we were able to bring our performance up to even just the average for a group of countries we consider our peers - the members of the Organisation for Economic Co-operation and Development (OECD).

To illustrate, I had one of my data analysts, Ed Foster analyse deaths during working life (from age 20 to 64). There are 2,562,000 normally resident New Zealanders in that age range.

In 2019 there were 5,787 deaths in that age group.

The top 10 causes of death were:

 Neoplasms (cancer)
 Cardiovascular diseases
 Self-harm and interpersonal violence
 Transport injuries
 Diabetes and kidney diseases
 Chronic respiratory diseases
 Digestive diseases
 Neurological disorders
 Other non-communicable diseases
 Unintentional injuries

Our method was to compare New Zealand’s performance to the OECD average and then, where we already exceeded the average, to a country that is like ourselves in income per capita that has the best performance (lowest working life death rate) for the cause of death.

In most cases, we found there are substantial gains to be made in each area.

If we assume some factors are influenceable in bringing New Zealand’s mortality rates down to that of the OECD average, we can say that 254 deaths could be prevented annually with 87% coming from the female population.

Most of the lives saved would be women who would benefit from earlier identification and better treatment of cervical and breast cancers. But we could improve our track record on the treatment of chronic respiratory disease too.

Turning our attention to the gap between New Zealand and the best-performing country for each of the 10 causes of death, we can see that over 2,000 lives could be saved annually but now with the majority (53%) coming from the male population.

We see this switch from female to male-driven primarily by cardiovascular diseases.

Of the countries that excel under specific causes of death; Israel, Ireland and the Republic of Korea have higher life expectancies than New Zealand handing them more weight to any recommendations made based on their modus operandi.

On the flipside Mexico and Greece have lower life expectancy values than NZ, making them less favourable as examples to follow, so we replace these with Japan for neoplasms and the UK for self-harm as better examples to follow.

Cancer is a great example. Our performance is above the OECD average for men, but well below it for women.

179 female cancer deaths per year could be prevented if New Zealand was able to bring its cancer experience up to the level of the average for the OECD.

With cardiovascular disease, we already perform above the OECD average, so we must aim higher.

Were we to improve to the best in the OECD we could reduce working life deaths by 595 lives per year – nearly half of our current annual experience.

It is a tough goal, but clearly achievable.

Self-harm and interpersonal violence is an area where there are significant reporting difficulties, but again there's a clear opportunity for reductions.

Our reference country, in this case, was the United Kingdom giving a potential gain of 128 lives lost annually.

Transport injuries is a category we should not be surprised that improvements are available – although not by as much as you might imagine.

Our performance is already above the average for the OECD, but if we were to improve to the level of Ireland, a not entirely dissimilar country, we could save 95 deaths per year.

With diabetes, the potential gains to the best performer in the OECD would save 69 deaths per year.

Overall, the available gains amount to around 2,000 deaths per year – almost 40% of our annual number of lives lost between age 16 and 65 each year.

Consider the benefits to communities, families, children, companies, and the country, of saving the lives of more than 2,000 people each year.
