What the numbers say
In 2023, New Zealand's tuberculosis treatment success rate (% of new cases) fell 11 percentage points on 2022 (from 87% to 76%).
Across the 20 yearly changes before that (2001 to 2022), the average change was +2.3 percentage points and a typical year strayed about 13.96 percentage points from that (the standard deviation). This year's change was 1.0 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 51 percentage points in 2002 and the biggest yearly fall was 21 percentage points in 2001. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2014 to 2023 there is no clear straight-line trend: a straight line explains 2% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures
Tuberculosis treatment success rate is the percentage of all new tuberculosis cases (or new and relapse cases for some countries) registered under a national tuberculosis control programme in a given year that successfully completed treatment, with or without bacteriological evidence of success ("cured" and "treatment completed" respectively).
Regional and income-group figures are computed by the World Bank as a weighted average.
