Watch: All Blacks using blood biomarkers to improve performance
Kick-off: 7:05pm Saturday 19 July
FMG Stadium Waikato, Hamilton
Live blog updates on RNZ
The All Blacks were in for a surprise after starting a blood biomarker programme last year, finding out that around the third of the squad is lacking in Vitamin D. Patrick Tuipulotu, one of the affected players, said he was "being a bloke" by not even being aware of what a vitamin deficiency was before he was told.
"I think as men we really get sucked into just saying everything's okay, but I think it was quite a shock when we found out. You don't think of those things much, so [it's] very good just to get on top of it ... Staying healthy is the right thing."
The 52-test lock addressed the issue by taking supplements, as well as thinking about his overall diet.
"I was trying to eat well as well, to make sure I was doing things naturally. Anything I can to stay healthy," the father-of-two said, mindful that seeking medical advice was something New Zealand men are not great at.
"Getting checked, just having blood tests is a simple ... easy process. If we can do that early, find stuff, maybe then obviously we'll be around for families a lot longer."
Tuipulotu said that having a job that has a full time medical staff looking after its employees is something he's not taking for granted.
"When we come into the camp, we're pretty privileged. We're well looked after. We've got a talking nutritionist, trainer and a few other staff who stay on top of things for us. Everything's provided."

Blood biomarkers, which work in the form of regular blood tests, have emerged as accessible and cost-effective way of identifying health issues. Eight New Zealanders a day die from preventable illness, with men often delaying health checks until symptoms interfere with daily life. The blood biomarkers the All Blacks have been using are in response to the growing need for tools that encourage early intervention and proactive health management, however, they can be used as self-testing kits for the general public at home.
Biomarker testing benefits for elite level athletes like the All Blacks include early detection of potential issues, identifying nutritional deficiencies and hormone imbalances, and injury prevention - by tracking markers related to muscle damage and recovery.
Team nutritionist Kat Darry said that they'd had some "incredible results".
"They were really, promising for us to really help a player optimise their performance and their health. So that was the whole ethos behind it all was, how can we make the player be the very best in performance and recovery, but also through health?"

Darry said that Vitamin D deficiency is caused by not enough exposure to sunlight, but it's not as simple as just going outside more.
"The darker your skin, the less Vitamin D you absorb. And so that was primarily the players that had the lower Vitamin D … a lot of it is down to the sort of sunscreen. But there's also different types of foods that we can eat to help supplement that a small amount. It was really putting them on a course of supplements, really helping them with the nutrition around how they can help with that absorption and just making some subtle changes over the course of the year."
Darry said that the lessons learned from the blood biomarkers was part of the evolving nature of sports medicine and nutrition.
"I guess one of the key things is that we're not just looking at individual blood (tests) in isolation. What we're trying to understand is, are the relationships appearing? So for example, if you're low on Vitamin D, are we seeing high cholesterol, are we seeing a higher cortisol? Are we seeing relationships of all these bloods together as opposed to in isolation? And so it really just made us consider our recovery processes."
Tuipulotu certainly wasn't deficient on Saturday night at Sky Stadium in Wellington, playing a big role in a dominant All Black forward effort that set up a
43-17 win over France
. With Scott Barrett out of the series with a calf injury, it's likely he'll be returning to the field when the teams meet in the third test in Hamilton this weekend.

Three more cases of measles detected in Wairarapa and Manawatū, bringing total to eight
The patients have been in quarantine, but one may have been infectious before this. (File photo) Photo: 123rf Another three cases of measles have been detected in the lower North Island, taking the latest outbreak to eight . Two of the latest cases in Wairarapa and one in Manawatū, were connected to the others in Wairarapa and stemmed from overseas travel, Health NZ said. The patients had been in quarantine, however, it was believed one person may have been briefly infectious beforehand. Health NZ had identified six new locations in Feilding that the potentially infectious person visited last Friday, Medical Officer of Health Craig Thornley said. The risk to the public was considered low, because the visits were brief, he said. "We are however advising anyone who may have visited the Feilding locations at the same times as the case to monitor themselves for symptoms, such as a high fever, cough, runny nose, sore eyes or a rash that spreads down the body." The new locations of interest are: "If anyone is concerned, they may have symptoms, or needs advice, they should contact their GP or usual healthcare provider or call Healthline on 0800 611 116 for free support and advice 24/7," Thornley said. Measles symptoms usually start within 10 to 14 days after being first exposed to the virus, but can start anytime between seven to 21 days. The rash develops three to four days after the other symptoms and appears as pink or red spots or bumps which start on the face before moving down the rest of the body. The rash is not usually itchy, but can last for a week or more. Thornley said the best protection against measles was vaccination. "The best form of protection against measles is to get vaccinated with two doses of the MMR (measles, mumps and rubella) vaccine after 12 months of age, which is safe and effective for 99 per cent of people."

'Mark your own homework': Healthy Homes checks under fire
By Bella Craig of RNZ Like drivers issuing their own warrants of fitness - that's how building experts and renter advocates describe the new Healthy Homes Standards. Since July 1, all rental properties across the motu have been required to comply with the new standards, which set minimum requirements for heating, insulation, ventilation, moisture ingress and drainage. But who gets to say whether a property is up to scratch? Well, with no certification required in order to complete an assessment, the role could technically be filled by anyone. This has prompted calls for an independent certification system. Ideally, under the new standards, damp and draughty rentals should now be a thing of the past. But the New Zealand Institute of Building Inspectors isn't convinced. Chief executive Graeme Blissett, said the standards contain several loopholes. Not least, that anyone can label themselves a healthy homes assessor. "It's a huge problem, because there's no one looking at what they're actually inspecting and writing reports on is actually correct. "There are no guarantees because no one's double-checking what they're doing, and I believe that if you're charging $150, $200 to do a healthy homes inspection on a house, you're not doing it correctly." It doesn't take long to find companies offering Healthy Homes assessments - a business was found online, offering to carry out a certification for around $200. But Blissett fears that without certification, many of these businesses will prioritise "quantity over quality". He said he's seen several certificates that ticked off each of the standards, despite the properties falling short. "The tenants [are] usually up to speed with these sorts of regulations and rules, so if the landlords do it on their own property and they get it incorrect, and the tenant finds out about it or talks to someone, and they've got a little bit of knowledge on it. There is a chance for them to be taken [to] the Tenancy Tribunal. "I believe there's fines of like $5000 or something like that for non-compliance." Renters United President, Zac Thomas, said the Healthy Homes Standards are a positive step towards a warmer and drier housing stock. But he's also concerned about the assessment process. "There is a mark your own homework situation where landlords don't even need to use an independent assessor in the first place. They can say that they are healthy homes compliant, that's the first thing. "But then the second thing is they can get this assessment from an agency that in many cases won't actually be complying or assessing to the standards as they should be." Thomas said that if the checks were completed by qualified assessors, it would give peace of mind to both landlords and tenants. "A renter might go, 'hey, please show me your healthy homes compliance.' They might be worried that the house is not compliant, and the landlord will probably show this, and then they might go, 'Oh well, I guess I have nothing to complain about'. "In reality, if there was a consistent standard, tenants would have the confidence to say, 'Okay, like this does meet standard, therefore I don't need to worry about going to the Tenancy Tribunal." University of Otago Professor, Lucy Telfer Barnard, said that as winter rolls around, if houses aren't up to standard, it's the tenants who face the consequences. "The tenants may not necessarily initially know that's why they're feeling unwell, but then if they do start to wonder, there's whole process that they can then have to go through to get those standards met. "To have that after the fact when they've moved in, in good faith, thinking that the property meets the standards, really isn't fair and puts a whole burden onto people." Landlords who fail to meet the Healthy Homes standards can face fines of up to $7200. Owners of six or more rentals that do not comply could be hit with $50,000 fines. A statement from the Ministry of Housing and Urban Development said they don't assess how landlords achieve compliance, and there is no licensing requirement to undertake Healthy Homes Standards assessments. Moving to this sort of "WOF" scheme would be a big undertaking with significant costs and impacts. It said landlords need to satisfy themselves that the person they hire is suitably experienced and can undertake the required inspection or work to an acceptable standard. If a tenant thinks the property they are renting is not up to standard, they can make a complaint on the Tenancy Services website or apply for a work order from the Tenancy Tribunal.
