2% is an arbitrary target. According to Volcker in his autobiography its has its origins in an offhand comment in a news story from then RBNZ governor during a bout with inflation that they would be happy if they brought inflation down to about 2%.

I mean yeah, but the trajectory is kind of more important.
You want to look for a rate of change here. Inflation is significantly lower than a few weeks ago.
