Puberty blockers: why politicians overriding doctors sets a dangerous precedent
The government’s ban on puberty blockers undermines clinical expertise and targets trans youth with a policy that lacks evidence, consistency and fairness.

There are excellent expert comments here on the NZ government's puberty blocker ban.

Horrible political meddling in healthcare in Aotearoa. "To me, this is basically cursing an entire generation of young transgender woman to social stigma, to moving through this world and having to deal with so much - I don't have another word for it - violence."

Halt to puberty blockers curses 'young transgender women to stigma'
That's the reaction of a model who used puberty blockers as a teen to rules halting new prescriptions for young people.

The government's cruel decision to ban puberty blockers for trans kids is devastating. Yesterday was for grieving, but today I'm pulling myself up, wearing my most rainbow of dresses in solidarity with every trans kid & their whānau affected. I won't stop fighting.

This is upsetting on so many levels. Banning new prescriptions is extremely harmful and doing this during trans awareness week, a few days before the transgender day of remembrance just makes it so much worse.

#Conservation implications: treating hoiho as three subspecies changes the playbook. Mainland M. a. murihiku needs urgent, tailored action, and genetic rescue from subantarctic birds could risk outbreeding depression by introducing local adaptations younger than the species divergence.

Take‑home on disease: it’s likely host genetics + virus + environment, not a single mutation “on/off” switch. That’s why species‑wide genomics + ARG‑aware GWAS are so powerful here.

Selection scans also show the Southern subspecies have younger TMRCAs (signals of recent selection) in cilia‑related pathways; hair‑like structures lining airways that trap and clear pathogens. This could help explain why Southern chicks resist RDS.

Re: RDS on the mainland. A GWAS within the Northern subspecies and all subspecies flags candidate genes tied to immunity and respiration.

Using ARGs, we can trace population divergence across the genome. This “excess coalescence” plot shows when genomes begin to diverge. The timing aligns with the BEAST-inferred divergence windows, but using separate methodology.

Methodologically cool bit: we also used ancestral recombination graphs (ARGs) to time coalescent events & control relatedness in analyses. Hundreds of thousands of local trees support the divergence times based only on mutation rate (generations rather than years ago). #tsinfer #tskit #tsdate.

When did they split? Molecular dating points to ~5–16k years for the Northern vs Southern split and ~3–11k years between the two Southern groups, dating to before human arrival in Aotearoa NZ. (Fig. 3)

With Ngāi Tahu kaitiakitanga, three subspecies are proposed:
• M. a. murihiku — mainland “Northern” hoiho
• M. a. motu maha — Enderby (Auckland Is)
• M. a. motu ihupuku — Campbell Is
These lineages are evolutionarily independent.

We sequenced ~249 whole genomes 🧬 spanning the mainland and subantarctic Enderby & Campbell Islands. Result: three distinct genetic lineages, with negligible gene flow among them (See PCA/tree in Fig. 2, and migration rates in supplement)!

On the NZ mainland, there are <150 breeding pairs, and many chicks die from respiratory distress syndrome (RDS) caused by a 🦠gyrovirus (YPGV). Subantarctic hoiho carry the virus too, but don’t show disease. Why the difference?
