What the picker changes
  • Top topics digest — the cards score the selected period against the prior 4 weeks.
  • 12-week heatmap & outlet matrix — show the 12 weeks ending at the selected week (they slide back with the picker, they aren’t a fixed snapshot).
  • Per-topic volume / alias drift — same 12-week trailing window, anchored on the selected period.
  • Coverage gap quadrant — scores the selected period against the 12 weeks before it (not including it).
  • Anomaly cards — only show alerts the detector fired during the selected period. Quiet weeks legitimately show none.
What stays as-is
  • Outlet orientation strip / lean colours — context-only, drawn from the last 12 weeks of activity regardless.
  • Co-occurrence graph — recent-activity anchored, not picker-driven.
  • Source & topic profiles — all-time data for the topic; the picker doesn’t affect them.
Rolling 7 days is a sliding live window for “current vibes”; switch to Weekly to compare specific weeks side-by-side.

  • I don't know the answer to that question. I don't think it's probably wise for me to answer it. But what I do know is that what Labour did in their last term of government with RV21, with the mass migration programme, with no skill, no English language, no health checks, just if you're in the country, welcome to New Zealand. And if your family's overseas, bring them in, which put enormous pressure on our health system, our education system, our infrastructure. That's plus, hey, let's open the floodgates after COVID, and don't worry about actually properly verifying things. People are now feeling that. There is a lag effect of the hundreds of thousands of people that Labour allowed across the border without proper checks. So I understand how New Zealanders feel. That was a disaster, but I want New Zealanders to know we have massively tightened that up. I have gripped up the portfolio. I've put in English language. We are more fairly associating costs through levies on migrants. We've already done that. We are much harsher on acceptable standards of health and much harsher on, hey, you need to have skill, you need to have English language and you need to be a net benefit to New Zealand.
