IWIinvestor Mihi

Ko te waka o IWIinvestor tēnei e tuku mihi ki a koutou
kua mau ringa ki te hoe.

I tēra ka tere whakamua tātou kia tau tika ngā wawata
kei roto i a tātou katoa.

No reira ngā mihi nui.

Greetings from the IWIinvestor waka to all who have placed their confidence in us.

It is without doubt we will progress forward to achieve the desired goals we all seek.

Therefore, greetings to all.

Whakatauki - 'Proverb'

Te tangata tiro kau noaiho ki te tihi

Ka kore e pikautia.

Te tangata tū pakari ki ōna hiahia

Ka tū tiketike ki runga.

A person who is casual in his approach

Will never reach great heights.

A man who strives to succeed

Will be rewarded for his efforts.
