You obviously didn’t bother reading the article I posted the link to in post 1527 and especially this bit:
This factor played a role in the Australian and New Zealand deals. One reason why these deals have made so little impact is that they were designed to. In order to protect domestic farmers, full tariff-free access to the UK market is being phased in, over 10-15 years for beef and lamb, and over five years for dairy.
Some sort of protection for domestic producers is warranted, both in order to allow them time to adjust and on grounds of promoting security of supply. But not only is the time for adjustment excessively long but it would surely be better to give direct support to farmers rather than blocking out overseas competition.
This is particularly true because those most at risk of losing out from cheaper imports of Australian and New Zealand products are not domestic producers but rather other overseas suppliers to the UK market, principally producers in the EU. As cheaper supplies are admitted to the UK, they will have to lower their prices.
Also both the UK and New Zealand have higher animal welfare standards which is important to us Brits:

The Animal Protection Index ranks 50 countries across the world based on their animal welfare standards for farm animals, pets, animals in captivity and those used in research. In 2014, New Zealand, UK, Switzerland, and Austria were given the highest rating ‘A’. These ratings have recently been updated and have reduced for both the UK and New Zealand. The UK is now rated B, and New Zealand is rated C. Both countries are rated C for the category “protecting animals used in farming” which demonstrates that the animal welfare standards in farming are at a similar level. The justification for reducing ratings were topics similar to those discussed by the when it gave evidence in Westminster on international trade. It stated that the animal welfare standards in the UK and New Zealand are broadly equivalent, and that in some areas New Zealand standards may be above the UK’s. The RSPCA stated the UK was ahead of New Zealand in areas such as bans on sow stalls, more free range hens, and general cleanliness when it comes to poultry. However, the UK is behind New Zealand in terms of allowing non-stun slaughter, greater lameness in sheep, legal live exports, and poorer access to the outdoors for dairy cattle.
There are also differences in regard to humane slaughter and slaughter facilities. Since 2018, there has been a legal requirement for all abattoirs in England to have CCTV installed. There is also a legislative requirement for all animals to be stunned prior to slaughter, with the exception of those destined for consumption by people of faith. There is no requirement for CCTV in slaughterhouses in New Zealand. However, it is compulsory for all animals to be stunned before commercial slaughter. Encouragingly, the UK Government has confirmed that it will continue to approve slaughterhouses in New Zealand to ensure that the standards are equivalent to the UK’s and ensure the import ban on meat not slaughtered to UK standards.
