Being a younger executive, Hudson said he had an ability to break the mould.
"You have to be quite brave to tackle something like this and raise it in a position of leadership where traditionally the stigma around mental health is [that it's] a weakness and could be potentially career limiting and if you talk you're going to get judged," he said.
Xero is today launching a new 'wellbeing leave' policy, under which its staff can access personal leave for their wellbeing and mental health when needed.
Hudson, who leads a team of more than 1000 people at the accounting software firm in this country, said the policy would go some way to making people realise "it's okay to not be okay".
"Mental health is exactly the same as having a cold [and the policy means] you're able to take time to look after yourself," he said.
Around one in five New Zealanders are impacted by some form of mental illness.
Hudson said it's important for companies to address mental health as workers' performance can be affected when they are struggling.
"[Mental health] also has an impact on overall bottom line performance as well, because your ability to be able to bring your truer self to work when you're struggling is impacted," Hudson said.
"Without your people you don't have a business."
And while it might be mental health week this week, Hudson said the matters needs ongoing attention the other 51 weeks of the year.
"It shouldn't just be a one day thing, it should be an ongoing engagement across all employees around the country," Hudson said.
