WELLINGTON, May 27 (Xinhua) -- New Zealand government will deliver its first ever "Wellbeing Budget" this week, said Prime Minister Jacinda Ardern on Monday.

Instead of meeting GDP goals, this year's government budget is understood to be focused on social issues such as mental health, homelessness and child poverty.

"Mental health will be a cornerstone of the government's budget", said Ardern during Monday's post cabinet meeting press conference in Wellington.

"This demonstrates our spending parameters for this budget, which a lot of investment has been shared over the past months as we made announcements to tackle the long term challenges facing New Zealand and to improve the wellbeing of all of us," said Ardern.

The New Zealand coalition government is committed to putting people's wellbeing and the environment at the heart of its policies, including reporting against a wider set of wellbeing indicators in future Budgets, it is said in the last years' budget.

The New Zealand government will announce its annual budget on Thursday.
