When her sailing commitments increased, she moved to AUT to continue her engineering degree, and later began studying a Bachelor of Information Science at Massey University extramurally.

[8] Just before her ninth birthday, Aleh was impressed by the New Zealand victory in the 1995 America's Cup, and asked her father if she could learn to sail.

Aleh then began the road to Beijing, competing in the Laser Radial class (women's single handed class) with a string of successful results including a World Cup event win, and a silver medal at the Pre-Olympic Test Event in Qingdao, China.

Aleh trialled with Team Brunel before the 2017–18 Volvo Ocean Race but was not selected and instead joined consultancy firm Ernst & Young.

[10] On 26 July 2024 Aleh was announced as a flag bearer for the New Zealand team at the 2024 Summer Olympics, along with Aaron Gate.
