Blues prop Michael Tamoaieta passed away suddenly on Friday, aged 23.
Tamoaieta made two appearances in his debut Vodacom Super Rugby season for the Blues in 2018.
He is survived by his partner Helen and daughter Aihara.
‘Michael was a talented athlete and our focus is to offer our support and sympathy for the family, and we are supporting our team and staff, some of whom are currently overseas,’ said Blues chief executive Michael Redman.
NZ Rugby chief executive Steve Tew added: ‘Our sincerest condolences are with Michael’s family at this very sad time.
‘Michael was a valued member of the Blues and North Harbour rugby environments and had been part of the New Zealand Secondary Schools team.
‘We know his family, club and former school mates will be feeling this loss and our thoughts are with them all.’
