"It is unnecessary to rehearse in detail the applicant's repeated refusal over a period of seven years to comply with the orders of the court and his persistent efforts to delay the proceedings. This can only be regarded as a cynical attempt to deny the respondent her proper share of relationship property and, by a process of attrition, to force her to give up her attempts to secure justice," he said.
Despite "grave concerns" about the man's actions to date, Justice Randerson said it was in the interests of justice to allow the hearing of the late appeal, provided the costs and other conditions are met.
The former couple separated in 2009 after a 14-year relationship.
The man, described in 2013 by a judge as playing a "protracted game of chicken" with the High Court, lives in Australia and has businesses on both sides of the Tasman.
He was barred in 2014 from taking any further part in the High Court-leg of the relationship property fight and there remains an outstanding order for his arrest after he failed to met the terms of a freezing order.
Notwithstanding his attempts to slow the progress of the seven-year stoush, Justice Rebecca Ellis last October ordered the man pay his former partner almost $5.6 million
This amount was a mix of her share of relationship assets, as well as compensation and maintenance.
The woman in the dispute has name suppression and the identity of her former partner was kept secret by the Court of Appeal.
