How does NZ Labour compare to National on State Size?

Some readers of ours are writing to say that even though Prime Minister Luxon could not be bothered turning up to the single most important day in Parliament these past fifty years to debate the constitutional foundation stones of our country, we shouldn't give him such a hard time. The consensus seems to be that the thought of having Lock-Down Labour, Lost-Their-Moral-Compass Greens, and State-within-a-State Te Pāti Māori back in power next year is so unthinkable that by comparison Mr Luxon looks pretty good. They have a point. The Opposition's Coalition of Chaos hasn't come up with one sensible idea since losing power. Now the only brain in the Opposition, David Parker, can't bear his own colleagues anymore and is leaving Parliament. Having said so, David only uses the left side of his brain. Lets, however, be objective, stop the slanging match, and put numbers on it. I've not seen a more striking difference between left and right in terms of Real Government Consumption per Capita anywhere than the following graph, sourced from the NZ Treasury. We've highlighted the periods during which Labour versus National governed:

This graph makes National look like one of the most fiscally responsible governments in the world. Under PM Helen Clark's Labour, government consumption per capita rose by around 25%. Under PM John Key's National government it rose by 0%. Zero. It was held constant by Finance Minister English. Under Alice in Wonderland PM Ardern's Labour government it rose nearly 30%. Yes, Queen of Hearts Ardern stole the Tarts. By comparison, under current PM Luxon's National Government it has fallen and is forecast to fall more. To those saying this Blog goes too hard on National, isn't this a good news story about the New Coalition?
