The Partnership offers three classes of limited partnership units: Class A, Class D and Class I (each a “Class”). The purchase price per unit of each Class is equal to the transactional NAV per unit (i.e., the price at which transactions in the Partnership’s units are made) for such Class as of the last calendar day of the immediately preceding month. Until the Partnership has determined its first Net Asset Value for the corresponding Class, the subscription price for Units will be $10.00 per Unit plus applicable subscription fees. Units are generally offered for purchase as of the first Business Day of each calendar month, with economic effect as of the first calendar day of such month, except that Units may be offered and investors may be admitted as Partners more or less frequently as determined by the General Partner in its sole discretion.

On March 2, 2026, the General Partner and HarbourVest Partners L.P. (“Initial Limited Partner”) agreed to contribute $10 each as the Partnership’s initial capital subscription to form the HarbourVest Private Equity Secondaries Fund (TE) L.P. partnership. The initial capital subscription was received by the Partnership in June 2026.

In respect of certain classes of Units, the Partnership is expected to pay participating broker dealers and other intermediaries ongoing servicing fees (“Servicing Fees”) equal to a percentage of Net Asset Value per annum for the applicable classes of Units. Class A Units bear a Servicing Fee of up to 0.85%. Class D Units bear a Servicing Fee of up to 0.25%. Class I Units will not bear a Servicing Fee.

The General Partner of the Partnership currently expects to redeem Units as of the first Business Day of each calendar quarter, with economic effect as of the first calendar day of such quarter (each, a “Redemption Date”), using a purchase price equal to the Net Asset Value per Unit of the applicable Class (the “Redemption Price”) as of the last business day of the immediately preceding calendar quarter, or on such other date as the General Partner may determine (the “Valuation Date”). Unitholders may request that the Partnership redeem all or any portion of their Units. The Partnership may redeem fewer Units than have been requested in any particular quarter, or none at all, in its discretion at any time. In addition, the total amount of Units permitted to be redeemed per calendar quarter will generally be limited to no more than 5% of the aggregate Net Asset Value of the Partnership and its parallel funds, measured as of the last Business Day of the calendar quarter immediately preceding the Valuation Date. Units redeemed on a Redemption Date that is within 12 months of the purchase date of such Units will be subject to an Early Redemption Fee, for the benefit of the Partnership, of up to 5% of the applicable Redemption Price.

Summary Of Net Assets [Abstract]
Net Assets	4. Net Assets The Partnership, at the discretion of the General Partner, has the authority to issue an unlimited number of units of each Class (as defined below). The Partnership offers three classes of limited partnership units: Class A, Class D and Class I (each a “Class”). The purchase price per unit of each Class is equal to the transactional NAV per unit (i.e., the price at which transactions in the Partnership’s units are made) for such Class as of the last calendar day of the immediately preceding month. Until the Partnership has determined its first Net Asset Value for the corresponding Class, the subscription price for Units will be $10.00 per Unit plus applicable subscription fees. Units are generally offered for purchase as of the first Business Day of each calendar month, with economic effect as of the first calendar day of such month, except that Units may be offered and investors may be admitted as Partners more or less frequently as determined by the General Partner in its sole discretion. On March 2, 2026, the General Partner and HarbourVest Partners L.P. (“Initial Limited Partner”) agreed to contribute $10 each as the Partnership’s initial capital subscription to form the HarbourVest Private Equity Secondaries Fund (TE) L.P. partnership. The initial capital subscription was received by the Partnership in June 2026. Servicing Fees In respect of certain classes of Units, the Partnership is expected to pay participating broker dealers and other intermediaries ongoing servicing fees (“Servicing Fees”) equal to a percentage of Net Asset Value per annum for the applicable classes of Units. Class A Units bear a Servicing Fee of up to 0.85%. Class D Units bear a Servicing Fee of up to 0.25%. Class I Units will not bear a Servicing Fee. Unit Redemptions The General Partner of the Partnership currently expects to redeem Units as of the first Business Day of each calendar quarter, with economic effect as of the first calendar day of such quarter (each, a “Redemption Date”), using a purchase price equal to the Net Asset Value per Unit of the applicable Class (the “Redemption Price”) as of the last business day of the immediately preceding calendar quarter, or on such other date as the General Partner may determine (the “Valuation Date”). Unitholders may request that the Partnership redeem all or any portion of their Units. The Partnership may redeem fewer Units than have been requested in any particular quarter, or none at all, in its discretion at any time. In addition, the total amount of Units permitted to be redeemed per calendar quarter will generally be limited to no more than 5% of the aggregate Net Asset Value of the Partnership and its parallel funds, measured as of the last Business Day of the calendar quarter immediately preceding the Valuation Date. Units redeemed on a Redemption Date that is within 12 months of the purchase date of such Units will be subject to an Early Redemption Fee, for the benefit of the Partnership, of up to 5% of the applicable Redemption Price.
