I've warned Officials about this. They are getting close to a "restraint of
trade" in defining legislation in a way that looks like an employment protector.

Again, I've spoken to Officials about that. If you cannot freely export logs and
unfinished timber, you cannot establish a true market price for the timber.
Right now, rimu is competing with radiata in price for flooring. Thats fucking

Sounds too high to me. I would have thought that was more a rimu price

Newer technology should be considered here. But, as usual, if the price is
right, you can solve most issues:)

That is true of radiata here. But not oak, which is heavier and more dense here
than in Britain. Also, temperature has an influence. Radiata is much more dense
in Northland and the North Island coasts than inland or further down the South
