Former All Black Jonah Lomu joined the Mormon church earlier this year.
Lomu, 37, was baptised a member of The Church of Jesus Christ of Latter-day Saints in Wellington, according to the church's website.
He spoke to a gathering of church members and friends in Mangere in South Auckland in June about his life and beliefs.
Lomu said that despite some of the choices of his youth he always remembered that his mother had instilled in him the need to pray for guidance.
He said missionaries from the church helped answer questions he had been asking for many years and he and his wife felt that the gospel was right for them and their family.
Lomu was diagnosed with the kidney disorder nephrotic syndrome in 1995 and received a transplant in 2004. The transplant failed earlier this year and he now undergoes regular dialysis treatment.
Lomu hit the headlines with four tries for the All Blacks in a Rugby World Cup semi-final triumph over England in 1995.
He played 63 Tests in an international career which stretched from 1994-2002, scoring 37 tries before illness cut short a stunning Test career.
