A well-known scientist says New Zealanders need to stop burning wood, to help curb two of the country's silent killers.

Stats NZ indicator data, following a 10-year study, has found two air pollutants are quietly contributing to thousands of premature deaths each year.

The two pollutants of concern, linked with pollution from vehicles and fireplaces, are PM2.5 and nitrogen dioxide.

Auckland University aerosol chemist Joel Rindelaub told Tim Dower combustion products create toxic cancer causing chemicals.

Belief July's record tourism numbers is a reflection of an investment finally paying off.  

Stats NZ data shows 256-thousand-600 overseas tourists arrived during the month - overtaking pre-Covid numbers from July 2019 by 0.4 percent.

Rotorua Mayor Tania Tapsell told Andrew Dickens the effort from local council, regional tourism operators and the Government is finally bearing fruit. 

She says July is usually a quiet time, so the big win is the 70 percent jump in business events that keep Rotorua afloat.

So, the past week has seen immigration policies come to the force.

New Zealand First is signalling a tougher immigration stance, longer waits for residency and citizenship, a referendum to cap new residency approvals at 20,000 a year, and a 30-year population plan tying migrant intake to infrastructure capacity. 

Labour is also tightening its settings, extending residency qualification to four years and promising a Government Policy Statement.
  
But as economists like Bernard Hickey point out these policies miss the real immigration pressure.

New Zealand issues more than 230,000 temporary work visas annually.  

Largely for lower-paid roles on our farms in our kitchens and even in our beauty salons.
 
The temporary workers aren't here forever. But when they go, they're replaced but other temporary visa holders. 

This quarter of a million of temporary visa holders is still driving population growth, straining infrastructure, and suppressing wages.  

They come with problems that no-one is addressing.

Not for the first time politicians can't see the wood for the trees and not for the first time they then release policies that are primarily designed to get votes but not to address the issues.
